I am looking for recommendations on manufactures for a custom enclosed trailer. The primary purpose for the trailer will be to haul dirt bikes and be used as bunk house for kids/friends during races/trips. Guessing it needs to be in the 20' box range. Basically I would like the trailer to have everything a typical toy hauler has except for the kitchen and bathroom. Fuel station, water, awning, etc. Work bench, overhead shelves and cubbies for gear in the front, fold down seats on the sides, electric double bed in the back. Anyone know of any manufactures that either produce or could custom build something like this?
