Help!

I would proceed with caution and get yourself up to expert status on all of the weight parameters: Gross combined, axle, tow. You will be pushing the limits with that rig. I'm sure the truck can pull the trailer, but it's a bad day coming DOWN the mountain when you discover you can't stop the rig.

With 6 average adults in seats and towing my rig for a full summer jaunt, I'm 700# over GCWR with my Suburban towing a 19' Rockwood Roo (tanks empty). I was surprised I was over when I hit the scales. (Where did that weight come from...we packed light?!) I only proceeded because all axle weights, tongue weight and other parameters were still in limits. Needless to say, I drive VERY conservatively on mountain roads.

The Traverse does pretty well on the secondary roads where the speed is up to 55 MPH. I hardly even know its back there most of the time.

On the interstate where higher speed and wind drag is more pronounced its definitely a little underpowered on the hills. Its not unusual for it to rev pretty good to maintain 60-65mph up the longer grades. A little more torque would be nice, but in general its not the worst towing experience.

Here is a link to the NADA book value. As mentioned before, don't add in any of the "extras". Of course, this is just a guide and the actual condition can sway the price in either direction.

I still like the suggestion that I read on these forums a long time ago....keep your tow weight around 70-80% of the recommended maximum weight. You'll have a much more pleasant towing experience and the tow vehicle will last longer. It's said so often...it's not a matter of whether a vehicle can tow it, but rather do you really want to do it and push the limits.

Do check for water damage (soft floor) by the front sink at the small wall that separates the pass thru storage from the cabin. You can also tell by climbing underneath and checking that the waterproof membrane is still tight against the bottom sheet of plywood, water intrusion will make it sag down and feel spongy. I'd suggest bringing along a creeper, might feel odd using it but it beats buying a damaged unit.

Nada shows a bogus "dry" weight of 3426lbs.
so, it's actual UVW/sticker weight from the factory, will be around 3800lbs.
so, loaded for camping, it'll probably weigh at least 4300-4500lbs.

now your Enclave's 5000lbs. towing capacity is rated with only a 150lb. driver in it. any other passengers or cargo in the car, will lower that 5000 number by each of their weights.

bottom line: you'll be at or maybe over the max capacity of the Enclave.
you'll have to load light and not carry water.
but stay away from any mountains, you'll burn that Buick up.

I wouldn't touch it. My Antigua is a twin of the 21 SB. The GVWR on my trailer is 5000 lbs; fully togged out, mine is north of 4500. The tow rating on the Enclave, WITH the tow pkg., is also 4500. That's for the FWD model. Add AWD, it'll be less. IF Buick even allows it with AWD! My Durango has 50HP and 105 lbs of torque on the Buick, and I am rarely unaware the trailer is back there! And with the Enclave being a unit-body vehicle, I would stick with something much smaller.

Believe it or not I did see a Buick Enclave towing a 28' Airstream this summer.

So how is the traverse towing the 18sb in the green mountains? Down south in the pokes our V8 trailblazer had plenty of problems towing the htt.

IMO, that price seems a little high for late in the season sale. Have you checked to make sure its been well maintained and is leak free? Any signs of water intrusion are bad for a trailer. I would make sure the caulking on the roof is in good shape meaning the previous owners kept on it.

I have a similar TV to yours (Traverse), but my 18SB is about 800lbs less. Mine tows ok and I have never felt unsafe but it could use more low end power.

I think you will be very close to maxed out in every weight with that trailer and TV. You will need to be very careful in how much stuff you bring along. It will probably be ok on lower speed roads, but it will not be too fun on hilly interstate. I would plan on a larger TV in the near future and I wouldn't plan any real long trips.
