Can't access the power dolly site but will try back.
Outdoor RV might work and I"ll research more. Looks like the floor plan I see has 2 doors.
My ''site'' will be on the property of a friend -- surrounded by palm trees on one side. Currently have a Class C I can drive into the site -- door and awning on the passenger side and is next to a palapa (carport type area with palm roof).
Rear door is not a problem, ideal is door on driver side. Don't need bunks maybe convert into something else. Length of Trailer I need is about 30' max.
Thanks everyone for the ideas.
