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 ...
That will be abut 8k loaded for a long weekend with 1000-1100 pounds of TW. Verify your receiver limit supports that. Add weight of your family to TW and verify your Expy has enough payload per driver's door Tire and Loading sticker.
