hello, I made a model of a 4x8 with 4 ft high ceiling it's a overland camper. I can't build it right now but if you want to do it. it wouldn't be hard to build and it would be a fun diy project for anyone with the money and time to build it.
rough estimate of $150 - $300 to build it with a used trailer more if you build the trailer or buy one. Harbor Freight 4x8 trailer will work for this project.
Have fun building! if you want to ask a question put in comments.
