Anyone out there have any experience or information on this 5th wheel toy hauler? Good. Bad. Indifferent? Looking at buying one, and know next to nothing about toy haulers. I did ask if the coupler would accept a gooseneck hitch without damage to the trailer structure or the warranty on the vehicle and the salesman said no problem. I plan on getting that in writing if I end up buying. Looking for advice from someone who's been there, done that. Thanks
