I am close to purchasing a 2020 Keystone Cougar bunk house (29BHSWE) and will be pulling it with a 2018 Ford Expedition Limited Max. Tow capacity of 9000lbs. Weight of trailer is 6,810 dry and GVWR ...
Usually the cargo carrying capacity of the tow vehicle is the killer. My Tundra was well within the CVW of the trailer, but with only 1,387 in cargo capacity, the truck I was alway a few hundred over every time we towed.
