Back from Montana, Ohio, and Maine

Trip East was informative. The BOSP worked well, except when we had significant wind. Without wind, speeds of 70 and passing at 75 was of no consequence. When the wind built up, slowing to 65 or 60 dampened the movement. We did have a few experiences where 55 was required. It was usually where both wind and road condition resulted in a negative influence on rig stability.

It seemed that impact from the wind was significantly changed by passing rigs. When there was no wind the impact of a big rig was minimal unless the passing speed was excessive and their aero was bad. Livestock big rigs are terrible on both counts. The direction of the wind was also a consideration. We had one area where the wind was on the passenger side quarter and the influence of passing rigs seemed to reverse sequence from normal. Interesting also was that in some wind we had a more stable tow along side a big rig as it sheltered us and more lateral movement when small vehicles disturbed or amplified the force. A very informative experience, but still significantly perplexing. We do not see the trailer swaying. We just feel the lateral movement of the rig.

Please, post your experiences with the BOSP. Your input is appreciated.

Pat,

AW - any chance you have recent experience with the BOSP that you would care to share? Pat

OK - just got home this afternoon with my new trailer and BOSP.

2016 30' Flying Cloud rear queen w 16" Michelin LTX tires
2014 Ram 2500 crew cab short bed diesel 4x4
longest BO stinger (forget the part number)

I have the hitch head one hole up from the bottom, link 9 on the chains, 1000 bars.

Considerable flex in the bars (good), trailer is level (good), truck is down about 2.5" in the rear with the bars tensioned (inconsequential given the weight of the diesel in the front IMHO).

The rig drove great - no sway and no push/pull except for a couple of cases where I was passing one truck (car hauler, no less), being passed by another semi and had another truck in front of me - turbulence city. There was minimal wind, so not sure how that would play. Speed ranged from 65-75 MPH.

The rig felt a bit different than the old trailer (a 25') with the same truck and a ProPride (that I sold with the old trailer). I didn't have 100% weight restoration there either due to the stiffness of the rear suspension. The truck did not get the shock/feedback from the trailer with the BOSP - this was also apparent in the appearance of the trailer interior when I stopped. Nothing moved - this is the softest riding hitch I have used (very good).

I know there has been a lot of angst over the performance of this hitch, but I have no concerns about the behavior on my truck and trailer. It was a very relaxed drive from Gulfport, MS to Orlando. At no point did I think "the ProPride wouldn't have done that".

I haven't checked the tongue weight yet (need to find my Sherline scale), but I'm guessing about 1000# based on the rear suspension compression without bars. The trailer was basically empty, but did have full propane cylinders and a full freshwater tank.

K&B Really interested in your experience as you tow with the BOSP. About 90% of why I like the BOSP is the softness of the ride, so I get it. So..... 1) how much weight is the BOSP shifting forward? At 9 links, maybe not much. 2) what is your impression of the BOSP in the wind? 3) how does it compare with the PP after you have a few miles and the opportunity to think about your experience? Welcome to the BOSP club. Pat

9 links from the free end of the chain - there is only 2 1/2 links showing below the bracket. It makes a significant difference in the ride height of the rear suspension so I'm sure weight transfer is taking place. There is no way I could go to 10, I would never get enough lift to get the chain to catch on the bracket. It is a real struggle with the 3k Atwood jack AS installed. I ordered the 4K version to replace it.

The suspensions on these HD trucks are too stiff to expect WD to work like on a softly sprung 1/2 ton SUV without making the bars so stiff that the trailer (and you) are beat to death.

I would not be worried about increasing the weight transfer if you are happy with the way the rig handles. Additionally, I would be surprised if you needed more. Nine links from the loose end is a lot of jacking on 1000# springs. Interested to hear your experience after you have traveled a bit. Happy trails. Pat

We have an International 28 and tow with a 2014 Dodge Durango V8 Hemi, BOSP with 1000# springs (3 dots) on the 9th link from the free end. Dealer who set it up recommended the 8th link. TV seems to be a little more level with 9, so we've stuck with that. Haven't noticed much difference either way while driving.

Getting close to 5000 miles on it, in 9 western states so far - tows great.

It was suggested I weigh in on this post. I started a thread a year ago when, like a lot of newbies, I was figuring out which hitch to buy. Here's my take on the Blue Ox:

Well...It's been a year since my first post and we've wrapped up our first season. First of all, thanks to everyone who helped out with information. It was all consumed and it was all considered. Here are my thoughts after maybe 8 or 9-thousand miles of towing this summer.

First the tow vehicle. 2012 Jeep Grand Cherokee, 8 cylinder gas Hemi. Very happy with the choice. Averaged about 14.5 - 15 mpg on the interstate doing about 65. After a couple of Lance Campers I can live with that. Some suggested the wheel base was a little short. I personally experienced zero problems with it. Get the backup camera.

The hitch. I ended up with the Blue Ox. Again, thanks everyone who weighed in. I can't prove the negative so I don't know if I would have sworn by the Hensley had I bought one. What I can tell you is that hitching up, particularly with the back-up camera, is very easy. Even without my wife helping it's a five minute job. Maybe ten. You get the idea. Once you have the system down it's very simple, relatively quick and very secure.

The longest trip of the summer was from Missoula, Montana to Austin, Texas to Minneapolis, Minnesota, to Missoula. Right around 56-hundred miles. We encountered torrential rains, winds of maybe 25-30 mph, dust storms, curvy mountain roads through the Ozarks and the Blue Ox was great. That's not to say there weren't times I was more than aware that I was towing a trailer in less than ideal conditions but I never felt I was out of control or over my head. Again, I tend not to travel over 65 mph. If you regularly do, my experience may be different from yours. I don't know what to tell you about that.

Love the Flying Cloud. A few little things to have the dealer fix this winter but all in all such high build quality as compared to the Lance Campers.

Again...Thanks for all your input and safe travels.

I should mention, in answer to a question, that I'm towing a 19' Flying Cloud with my Blue Ox.

Blue Ox on order

After a week of intensive research I sold my monster Hensley and ordered me a new Blue Ox Swaypro yesterday. The Hensley is a very functional hitch and I have nothing bad to say about it but it's just too much of too much for me.... glad it's gone. I did consider the Andersen No Sway but it seemed a little to light for my 30ft Classic. For what it's worth I talked to Andersen via email about the issue of the Andersen damaging some couplers ... they told me that is a myth and is not true. I have the quote saved I can forward in a private message if anybody is interested.

Just a heads up on the BOSP with HD trucks (based on my experience) - you really have to lift the truck/trailer high to get enough "slack" to engage the desired chain link in the rotating bracket. The issue is keeping the chain engaged while attempting to rotate the bracket.

My 2016 came with an Atwood 3000# Premier jack, and it was not robust enough to raise my 30FC and Ram 2500 CTD high enough to use link 9 (from the open end) on the chains reliably. The gears would disengage on the jack (as designed feature to keep from tearing up the jack). I replaced it with the 4000# model with much better results.

It's not a matter of a bigger lever, but one of the basic geometry of the BO design.

Interestingly, the instructions for the Atwood jack mention this very issue with HD trucks and recommend the heavier rated model.

How many links are there on that chain?

Some folks count from the chain end and others from the u-bolt on the bar end. The link reference from the chain end had me perplexed as we count the other way. So, I took the time to count links in both directions. We use 9 links from the bar, which is 7 links from the chain end, for a 16 chain link total. These are the 750 lb (2 dot) bars. Pat

As suggested by Blue Ox when I called them I count 7 links from the end of the chain and hook the 8th in the bracket.
