Here's a thought, go buy yourselves a "bed in the bag".
My wife buys these, they come with all the fixins to make a bed, use the sheets and pillow cases for the trailer.
Keep the plastic bag the sheets and comforter came in, usually these bags have a zipper.
Anyway you can toss all the hose and connections in the bag. Then toss this in the back of the truck when your Towing/moving.
Just a quick thought actually as my wife just
bought a new "bed in the bag" for this years camping.
