Spend your days at the campground kicking up mud with this toy hauler in tow! once you've unloaded your toys from the ramp door, you can use the 60 gallon fuel station to fill up and head out on a trail! The overhead bed provides a place for guests to sleep, and the optional Happi-Jac rollover sofas and a table with a top bed will give you the option to add even more seating and sleeping space. There is even an optional half bath here if you choose to make this space more accommodating. Head to the middle kitchen and living area where you'll enjoy generous counter space to prep meals, a spacious 20 cu. ft. refrigerator, an L-shaped sofa, plus a hybrid desk/dinette that will serve as a dining or working space.
