Get ready for a lot of fun when you head out to the off-road park, a special event, or a long trip with your toys! You will love the garage with the Fast Ramp rear ramp door, the Ram-Air garage vents on both sides, the 2,500 lb. rated flush-mount tie-downs and the protective diamond plate on the garage sidewalls. This area can become a bedroom or an extra living area if you want to add Happi-Jac rollover sofas/table with a top bed option, plus you will already have a half bath for convenience, an overhead loft bed plus a flip-up pet dish for your furry friends. The living and kitchen area is spacious with dual slides and a kitchen island with bar stools, a free standing dinette and theatre seating. The fold-down side patio offers a great place to relax outdoors above ground, and there are many more features to enjoy plus several options to customize your fifth wheel.
