Maybe look at some of the light weight campers. I have a shortbox GMC 1/2 and put a Polomino Pop Top camper on it. It only weighs 900lbs, and is under 7'6" when closed. Save me a bundle on excessive height ferry fees. I did install airbags on it though because I tow a driftboat with a motorcycle strapped to the front of the trailer and needed to get the truck level for proper headlight function.
