Towing with 2015 Suburban

We are buying a 2018 Classic and are being told our 2015 Suburban will tow this trailer (with proper hitch) with no problem. My calculations say we are close to the max without loading the trailer or tow vehicle. Anyone else with this setup care to chime in?

A few questions for you

30 or 33 classic?

Tire size on the Suburban?

Axle Ratio?

Which Suspension pkg do you have? Z71 comfort ride standard?

Sorry about that lack of info.
Airstream 2018 classic 30'
Tire size on Suburban P265/65R18
Axle Ratio = 3.42
Suspension, not sure, it has the max trailering package which includes the 3.42 axle, trailer brake controller, 2 speed transfer case and suspension package. it also notes on build sheet GVW rating 7,500 LBS.

Though there are SUV's we now prefer over the Suburban only one has as much space and there is no more well proven tow vehicle. In the 80's and early 90's more Airstreams were towed with Suburbans than any other vehicle.

Those thousands of Suburban's that towed Airstreams in the 80's and early 90's had considerably less power than yours with only a 4 speed transmission. People towed everywhere with them so it can be done and they would find the performance of yours simply awesome. However if you feel you have to climb the Interstate grades in the Rockies at 70 MPH then you do need more power. If you can live with 45-50 MPH for a small percentage of your driving your Suburban will be just fine.

The older Subs actually handled better than the new ones, they sat lower and had firmer suspensions along with a better tire and wheel combination though we still improved them. It seems the whole world is upside down, 30 years ago a truck was firm and Cadillac floated down the road. Today the truck floats along and the Cadillac has firm dialed in suspension.

The good news is you can pretty easily tighten up the handling on your Suburban. Having driven them before and after I would make the change even if I did not tow anything.

First I would install Bilstein shocks, if it has Nimovac or Air rear shocks then just do the front shocks.

Second change the tires to P255/60R x 18" XL (extra load) Pirelli Scorpion Verde's. This smaller tire fits the rim much better and has a firmer construction so sidewall sway is fraction of the current tire. The down side is that your speedometer will read 63 MPH when you are traveling 60. Upside you will have in effect a 3.60:1 axle ratio.

Like any tow vehicle setting the hitch up properly is critical. If you would like a couple of sheets explaining the process send me an email andy@canamrv.ca.

I hope this helps.

Check out the older 2500 3/4 ton models, with a choice of two engines. After pulling my )albeit small) 20ft FC with my '12 Tahoe or '05 Yukon (both with the 5.3L engine) I wanted longer wheelbase. Searched for awhile and found an '11 3/4ton 'Burb that had been leased new by the government. So the interior was spotless, ditto the outside other than scratches on the hood from all the briefcases spread out there. It has the smaller 6L engine, but what a difference in ride with the stiffer 3/4ton frame. I feel a lot safer. Look into it maybe. Safe travels. jon

2017 27fb (7600# dry, 9000# with all my shoes) here in the Rocky Mountains. Started with my almost brand new 2014 1500 4x4 suburban. Spent $5k to put in a 3.73 gear ratio to give a 10000# tow capacity. Slow uphil, 45mph and 4000rpm, fine on the flats, sketchy on the downhills. I also had almost zero payload on the suburban for bikes and kayaks and etc... broke my heart as it was my 5th suburban and almost 1 million miles over the last 20 years, but went to a 3/4 ton diesel. Towing and payload are awesome.

I had the same question two years ago. Since I go to the Rockies every other year I decided that the Suburban was not the correct tow vehicle. I love my Suburban but I got a Silverado 2500HD for towing the Airstream. It does a great job - hardly know that the Airstream is behind it. I still have the Suburban.

Hi

What else (other than yourself) do you plan to load into the TV? For some the answer is "nothing". For others the list is still going strong as it passes 1,500 lb. The number you need to look at is the "full load" number (worst case). If you happen to have several configurations, what's the heaviest one?

Next up (but not quite as significant) is the load in the trailer. You can toss another ton into the empty Classic and still be "ok" on trailer axle weights. Some people will never get there. Others seem to be within 500 lb of max "most of the time".

How heavily do you want to modify your TV? In other threads, various people (none of whom have spoken up in this thread) recommend a specific tow vehicle as being "just fine". A while later they rattle off a list of modifications that impacts 90% of the drive train and suspension. You *can* do a lot to upgrade any TV and it will help. I'm not sure that it's still the same vehicle after a dozen or two mods ....

TV tire change is hardly major. Better shocks, same.

Worthwhile, given the advisor.

Or, do ones own research. But, why (per above).

I think you should not stress about it till you try it, I think you will find that it's just fine and if not look for a good deal. But if you're itching to spend more money go buy the ultimate towing vehicle, we would love to hear what you get!

Andrew T.'s towing advice is the best you will ever get, much of the rest is 2 cents worth suggesting you need to spend thousands and thousands. Lots of that goes on here. With the exception of the fellow advising you to try what you have.

Something else. Call your Chevy dealer and ask him to get you the tongue weight limit of your receiver on that Surb. If your max tow wt is 7500# then your tongue is probably 750#. Not enough for your 30. They will call it a class 4 hitch, but that capacity varies. If you decide on your Surb, do yourself a favor and at least put a Curt class 4 on there with plenty of reserve. Better yet, buy a 3/4 ton vehicle and do it right.

Very sad, but very true. I still fondly remember my Dad's 1981 3/4 Scottsdale 4x4, 350 4sp stick, with roll down windows, bench seat and a regular cab/ long box; now that was a truck!

What a pity that the only "truck" I can buy, I have to buy from a Toyota dealer in Saskatchewan Canada, but I can't drive it in NA, even though it meets all the regulations.

Cheers
Tony

i have a 2016 gmc yukon xlt and it does very well for my 22 fb. I would not attempt to tow a classic with it on a long term basis. will it tow yes. but over time it will ruin your transmission . u will struggle up hill and likely down. u will feel like the tail is wagging the dog. to be safe u should not start with the max tow weight when u then have to add people and gear. when I bought my 22 they said I could pull with my then brand new Buick enclave. I had it tow equipped and all then took it to the gmc dealer who set me straight about how it would void the transmission warranty . I have also talked to many educated people about why it should not be done.. that is why I now have my beautiful Yukon. have a wonderful time traveling whatever j get and be safe

In my opinion the suburban is not manufactured to tow a 30 foot Classic, I had one and I tow it with a #3500 SRW diesel GMC. If you spend money for a top of the line trailer, why do you want to buy tires, and shocks etc. and still have a truck that is a passenger car. Trade in the Suburban get at least a 2500 and enjoy going anywhere with a full trailer and a full tank of water.

I hear the SOS about traveling with no water and so on.

Safety is job # 1

enjoy your new trailer I just picked up the 33 and love it

Unfortunately your GM dealer likely had zero experience towing an Airstream. So he just gave you advice that put him at no risk.

From a handling and safety point of view the Enclave is quite a bit better than the Tahoe. It has a longer wheelbase, shorter rear overhang, lower centre of gravity, independent rear suspension and better tire and wheel combinations.

We have hundreds of customers who have been towing with Enclaves since 2008 so far zero transmission problems.

2017 Escalade owner here with the same mirror issue at first. I got the Dometic Aero3 tow mirrors (see attached pics) and they work like a champ.

As for the original post (since the Escalade and Suburban are cousins) we checked with 2 Airstream dealers as well as the Caddy and sister Chevy dealer. Consensus was that the International 27FB should be the highest we go.

Several trips now, and the Caddy has been a monster, albeit we've yet to hit mountains.

Well, first of all thanks for the good advice given from everyone I love it! Second, we decided to change TV to a 2017 Chevrolet 3500 High Country. After our first initial tow with the Suburban and the fact that the weight capacity was at its limits we decided to beef up to the 3500. It cost us a pretty penny but we definitely feel much better about the load handling abilities we have now. Still have the Suburban because it is such a nice vehicle to load up all 5 of our grandkids and head out on an adventure. Thanks again!!!!
