The kitchen has everything you will need to create home cooked meals, as well as a kitchen island with two bar stools and a USB charging port. Grab a snack from the kitchen pantry and relax on the four-seat sofa slide with a stowable table to set your food on. The garage area has an overhead bed, the space to add the optional two Happ-Jac's with rollover sofas and table below, and it is prepped to add the optional washer and dryer, plus you can even add the optional half bathroom! If you would prefer to have a residential refrigerator, you should check out model 398M-R!
