Best Coupler Locks?
 

What coupler lock are folks here using? I like the sound and looks of the MegaLock, but they have so many choices that I cannot figure out which one(s) would best fit my 1960 Safari. Please post your experience with your coupler lock and the part/model number if you have it. Many thanks!

Is anyone using a lock on your AS?

I just use the one that Colonial Airstream supplied when I bought my AS.

Hey M3, try the search drop down at the blue bar. Use the google line and search on coupler lock and tongue lock. I think you'll find what you need in several threads already out there.

we bought this lock: Trailer Coupler Lock - 2-5/16 Inch Ball Mount, for Airstream Trailers - Clearwater Industries Llc LA52516 - Hitch Locks - Camping World

it fits over the rolled lip of our '72, and seems secure. Gives us some peace of mind.

Coupler locks are nice, well, sort of.

As long as the safety chains are still attached, a good thief can simply hook up the chains to a ball mount, then remove the jack, or retract it.

Takes 30 seconds and off the thief goes.

That allows them to move the trailer very quickly, to a place where they can then cut the coupler lock off, where no one is looking.

Probably the surest secure way, is to remove the wheels, but that can be very troublesome, as well as not totally securing storage safety.

Budget M3,
this year I purchased the below lock from ODM. Real easy to use and the only thing I worry about is forgetting to bring the key to unlock it when I go to move it to another location with the TV.

I've left the AS unattended at a few campgrounds this year for the last six months and every weekend when we return it is still there. A good thing. Most folks know who we are, but people do get busy so there is no sense in taking a chance.

FYI, I also use the BAL X-chock locks for no movement/stability and ensuring the rims and tires stay on the Unit. Not that there are bad folks out there, but just in case we are the "shiny object" I want to make it as difficult as possible for those tempted to look at SOB.

Well worth the money and I highly recommend the mega-hitch regardless of where you buy it. You can go to their web site and watch the video which compares a variety of locks. Best of Luck,

Did that before I posted. The threads I read just said "I got a ___ lock", but very little about the huge variety of locks out there or which models are better for AS.

I use 3/8" chain run through the wheels and around the axle and a decent padlock that is used behind the wheel. Available at any H-D dealer. You could run an AS on to a ramp truck (complete with hitch lock) in less time than it takes to type this.

Understood, Andy. I am looking for a few extra ounces of deterrence to discourage the "opportunist thief". Your insight has given me the idea to also wrap the safety chains around the coupler and use a padlock on those when the trailer is parked for any length of time.

Hmmm...I suspect the professional thief with a flatbed is going to get the trailer no matter what steps I take to deter them. The chained wheels are a good idea, though, to help deter the casual thief. Thanks for the suggestion!

Do you have a link for that item? All I can find is Megahitchlock...

MegaHitch is what I meant. Link is in one of the above responses...

May I ask if you are you at all connected to that company in any way, or do you sell their products?

I'm not associated with megahitch in any way other than as a customer. I bought one and think it is he best deterrent type lock for the hitch. Of course nothing is fool proof. Watch their videos on their web page. I know it is very well made. I can't figure out a way to beat it. Anyone had their AS stolen with one attached?

No connection at all. My comment is strictly based on other opinions read here on the forum.

Aage,
On being connected with the Megahitch Company, only as a consumer. As I mentioned earlier, I would be hating life if I had the go get the Airstream a couple hundred miles away to move it to another location (as we have found it is cheaper to leave it at one location and drive to it for the weekends without towing it), and forget the key either at the house or in the other car. That thing is not coming off.

We do have plan "B" so no worries about forgetting the key.

It is a good solid item and a great deterrent. If some one wants your Unit, unless it is hitch to you TV or in a closed storage space, anything is possible.

Good luck

Greetings,

I purchased a Mega Hitch coupler vault since I was told that it met the specs for my trailer. It arrived and was not very "loose" like it was supposed to be. I called the company and spoke with Mike who was more than helpful. The Airstream Megahitch uses a 2 5/16" ball and wouldn't work with my 63 since I have a 2" ball. Mike made a custom Airstream Megahitch for me with 2" ball that works AMAZING. He then shipped it to me with a box and RETURN POSTAGE to ship the old coupler vault that didnt work for me back.

Unlike several vendors in the trailer and Airstream world, this was unbelievable customer service. Return postage for free? Custom hitch? I told Mike to start offering this new style of hitch for vintage owners, and since it was just a week ago that this happened it is likely he hasn't changed his website yet.

I HIGHLY recommend Mega Hitch coupler locks. They are pricey, but you can't beat the security and customer service.

I just picked up this lock. It's a great deal at this price.
Amazon.com: Trimax UMAX100 Universal 'Die-Cast' Dual Purpose Coupler Lock

This may be a stupid question, but ... here goes. Are Airstreams stolen very often? Anyone have stats?

Great question! I'd also be interested to know which is stolen more often--older or newer trailers? Maybe the idea of a lock is just an overreaction to a threat that is minimal?

:) Hi, I wouldn't be without a coupler lock on my trailer. I use a Guardian G-37. Seems from what I have read here on this forum that older trailers usually in storage lots or on large properties have been stolen. Also seems that most were in Washington or Texas. Also a few were reported as stolen off of dealer's lots. [brand new] This is just from what I remember right now.

We used to use the Guardian G-37 which I think is one of the better lock designs available, but have recently gone to using the MegaHitch vault. As a non-thief, I think the MegaHitch would be a bit harder to overcome.

As noted above, Clearwater Industries (the MegaHitch manufacturer) does offer great customer service. They called a couple months after I purchased the lock to make sure it was working fine for me, at which time I asked to see if I could get more keys for mine as I somehow lost one of my keyrings. They looked it up and the keys were in the mail that day.

I've also ordered one for my parents' new teardrop. That thing seems to attract even more campground attention than an Airstream. :)

Here in Hinckley, Ohio three or four trailer were stolen in the last month. They weren't Airstreams but non the less stolen trailers.

An Airstream can be placed anywere, a back lot, a permanent campground and used. It dosn't need to have a plate or be registared. A fellow on Craigs list is advertising for the return of his Airstream stolen from a campground locally.

When was the last time you were stopped and they checked the trailer registration and plates?

You see older trailer advertised for sale cheap and when you inquire, they have no title. IE stolen years prior. Sometimes an owner missplaces it though or dies.

Airstreams are very expensive and will be stolen.

Are they stolen? About 4 or 5 from Texas last year alone.

Mega Hitch is the best in my opinion, and after watching the video of them blowing the competition's locks away (breaking into them or breaking them off).

AS Thift
 

My Hensley hitch has workes well as a theift determent. The theif can't figure out how to hook it up.

Good point! :D

Hi, all. I know this thread is a few months old, but I'm in the market for a hitch lock, hoping you can help me make the right choice. Several of you have mentioned the megahitch coupler vault. I checked out the website, which one is appropriate for my 1950's Airstream? The 1 7/8 or 2" model, or do I get the silver 'Airstream' model? For those who have purchased this lock, are you still happy with it? Thanks!

Sum, what size hitch ball do you have?

I'm pretty sure it's a 2"

...but I do like the looks of the 'Airstream' model (hey, it's silver after all). Or is yellow a better deterrent?

The 2 inch is what you need. My lock is yellow, I really don't know if that color is a deterrant or not. Do keep in mind that a lock no matter what kind will not stop a professional. Hopefully they will at least make some lazy scum bag go for an easier target.

Thanks, AWCHIEF. That's what I'm hoping, that the lock will give potential thieves pause. It sure seems like it would be a lot of work to remove- definitely not quick or easy!

After reading about these locks I bought this one:



All the lock does is slow the thief down a bit but a lock with a visible bar or loop is the quickest to cut off.

Guardian G-37 hitch lock
 

I just got my check returned from Guardian.02/06/13 The envelope was marked OUT OF BUSINESS. Bummer

Yep, that's the one I ended up getting too.

That one is the Masterlock 379 DAT, right? The price is hard to beat ($19.25 on Amazon tonight). Maybe I should start with that one then upgrade to the other one later. I just don't want to take any chances.

To Sylvr Slypr... Well at least you got your check back! That's crazy, the website is still up & running. I hope you find something better.

My envelope was inside the marked one and it had the correct return address for Guardian. I think I will give them a call to get to the bottom of this.

Yes, Sum75, it is the MasterLock. $19 is a good price, too.

FWIW: I've decided to go with the Megahitch Coupler Vault. Yes, as another poster stated, it is a pricier option, but it seems very well engineered and solidly built. Just placed the order yesterday and it's already in the mail. Coming from Oregon, just like my trailer will be next week! Funny coincidence. I wonder if it was manufactured here in the USA? If so, then certainly every dime is money well spent. Just my $0.02!

Is anyone using this lock?

Diversi-Tech Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers

it appears to be one that used to be branded Husky and i saw one on AS next to my new storage slot and it sure fits a lot better than my MasterLock that I had to modify to make it fit the lip of my coupler.

Hi, Goal

I think the downside to that style of lock is the exposed shackle, which is theoretically easier for a thief to pry loose or cut through. But as has been mentioned elsewhere in this thread (repeatedly, I think), a determined thief won't be stopped by any lock! Just hoping to make it a headache for them so they'll find an easier target. The one I ordered arrived a few days ago... I'm impressed by its heft.

AMPLock, they adversise themselves as The Ultimate Anti-Theft Lock!

Amplock, The Ultimate protection recommended by insurers

Thanks for the thoughts... did you order the one I asked about? I know that a determined thief is going to do what they are going to do but my storage space recommends coupler locks and i think a crowbar would probably remove my MasterLock one much quicker than someone could pry or cut this one off.

Mostly just hope that the crook would say... "well crap, one more thing I've got to deal with if I want to take someone else's property"..... because if they are criminals they are probably lazy as well as ignorant.

Best coupler lock I ever heard of, was a simple sign, located in 3 to 4 windows.

WARNING

THIS TRAILER IS EQUIPPED WITHA MOTION SENSING BOMB.

ANY ATTEMPT TO MOVE IT WILL CAUSE THE BOMB TO EXPLODE, CAUSING COMPLETE DESTRUCTION WITHIN 150 FEET.

:D:lol:

I have been using MegaHitch Coupler Lock for the Airstream for more then a year.It works well. It is heavy duty and is tough to get to the lock section as it is on the back side and tought to see.

Another thumbs up for the MegaHitch. Here's an image of the Airstream model. As Urnmor mentioned, there's a barrel lock on the trailer side. It can be awkward to get to, but it would make it hard for a thief to get in there.

I've used a Masterlock MLK379 for years on my boat then Airstream. I don't know if it's the best one, but it has been 100% effective thus far. It did successfully prevent the utility company from moving my Airstream without my permission while I was at work. However, they probably didn't have the same mindset of the typical thief.

I paid less than $20 for it 8 years ago and it's been outside ever since. The chrome finish still looks good and it functions perfectly.

Hmmm... Sylvr, does sound like the company has gone out of business. I went with the mega hitch coupler, seems really solid (it feels like it weighs 10lbs).

I use the MegaHitch coupler lock on my 2012 AS Flying Cloud. Watch the MegaHitch company produced YouTube video on how their lock is more effective than the other style hitch locks that are currently available.

The coupler/hitch lock (even the more expensive ones) will not prevent a determined thief. All they need is a pry bar or your safety chains to tow away *** unless you immobilize the tire/wheel(s). Suggest a short length of padded chain and an armored bicycle lock to tie either two wheels together or a single wheel and shackle ... much more effective IMHO.

The chains can just as easily be cut.

Removing wheels usually is the best, along with adding locking stud nuts.

That prevents reinstalling wheels.

Andy

Do you think the chain is adequate? I was thinking of supplementing my hitch lock with a trimax wheel lock- it's like the boot that police use.

Geez, looking over these posts I realized that I posted the wrong coupler lock. Here is mine. Got my DAT XXXX's messed up:

Interesting note. At the Sarasota WBCCI State Rally I learned that while traveling the trailer hitch latch should only be clipped shut with a clamp or something - not a lock. The reason... safety in the event or need of disconnecting the tow vehicle from the trailer. I just always used a padlock.

Out of curiosity, does anyone know someone who had their camper or trailer stolen while secured by a coupler or wheel lock (of any type).

The only folks that I know who had trailers stolen weren't using any kind of lock. Thieves just hitched conventionally and left.

Wheel lug nut locks assumed ...

Do not see any resent posts on this subject. Going with the Proven Industries lock made for Airstreams. Only a little concerned about theft, just want to be smart about the possibly.

We are new to all of this so any insight how this community thinks about security is welcome.

Thanks,

Hi, There! My trailer is in my driveway secure with the hitch lock I bought several years ago. It gives me peace of mind, although it maybe looks a little silly (mine is rather clunky looking and the paint is faded from the sun). My trailer is a work in process, which is itself probably the best deterrent (complete with Clecos running the perimeter down by the belly pan). Still I would buy the hitch lock again, it has been money well spent. My Airstream is an investment not just of money but of my time / blood, sweat, tears) and future plans... You can’t really put a price tag on that.

You definitely have the right idea to get a lock. I know of people (fiberglass camper owners) who went with the Proven Industries lock and are very happy. It seems incredibly secure and has a nice clean look/ isn’t overly bulky.

I can’t say what other measures you should take. I’ve read that wheel locks are a good idea, also they’re small and relatively inexpensive. A larger boot-style wheel lock is probably overkill for traveling but if your trailer will be sitting out in the open for long periods you might consider it.

Congrats on your trailer and happy travels! [emoji4]

Takes a handful of seconds to cut through a hardened steel lock with a CORDLESS angle grinder.

No, you won’t hear it.

Something beats nothing, but as Andy relates above, it takes an approach combining wheels, chains and a lock.

The one about locking lugnuts on a bare drum is great.

********

Proven Industries here as well. I really like that you can secure your safety chains with the lock as well. It is a bit pricey, but in the overall scheme of things...
