The spacious garage area is perfect for hauling your favorite toys, and the two entry/exit doors make it easy to get in and out. The front bedroom is a peaceful retreat, featuring a queen bed, wardrobes, and plenty of storage for your gear. Further in the heart of this unit, the U-shaped dinette is perfect for enjoying meals or game nights, and the pull-out trash makes cleanup a breeze. The kitchen is equipped with a microwave and 8 cu refrigerator, so you can fuel up for your next adventure. The theater seating is perfect for movie nights or catching up on your favorite shows, and the electric Happijac bunks provide a comfortable spot to rest.
