What does it take to tow it?
RV Finder’s estimate: it needs a vehicle rated to tow about 16,400 lb, with a fifth-wheel hitch. That is its 15,138 lb dry weight plus 1,200 lb for water and gear, rounded up to the next 100 lb. The listing doesn’t say whether it’s a fifth wheel or a bumper-pull. RV Finder judged it as a fifth wheel from its weights: ask the dealer. RV Finder shows whether it is within your vehicle’s published rating, from the maker’s own towing guide, and checks tongue weight and payload too. Confirm your numbers in your owner’s manual and on the sticker in the driver’s door jamb. Check it in RV Finder
