to the forum big_beau, glad to have you join us!
A quick forum search shows you're the only one that's posted about towing with an Enclave, but we do have other members with the same trailer, so hopefully they'll chime-in soon.
In the meantime, I'll offer some input ~~
The weight you're quoting for the 238ML is the "dry/empty" weight, as shipped from the factory. That # doesn't include the weight of factory options (if any), the RV battery,
LP (40 lbs), fresh water (8.3 lbs/gal), nor any of your camping supplies/clothes/food/toys, etc. Even with only 'the bare-minimum' supplies/gear, the trailer will likely weigh
about 4200 lbs once loaded... and that's a very conservative guess.
Specs for 238ML
Shipping Weight 3711 lbs (dry/empty)
Carrying Capacity 1689 lbs
Hitch 495 lbs (dry/empty)
Length 24' 11"
In addition to your towing capacity, confirm the Enclave's GCVWR, and check the actual curb weight & payload/load capacity of "your" specific vehicle as listed on the stickers (driver's
door area). Also keep in mind that Passenger Tires may affect handling when towing a heavier/longer trailer than your pop-up.
[Quote from Enclave Brochure] "Maximum trailer weight ratings are calculated assuming a base vehicle, except for any option(s) necessary to achieve the rating, plus driver. The weight
of other optional equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow."
Your concerns are valid -- and, once you do the math, chances are you'll probably need to choose a lighter trailer.
Good luck with your decision,
Terri, the Chevy co-pilot
