Insulation, power and plumbing drive the cost. Builders quote after seeing your plan. Ranges are what builders commonly quote in the US, not offers.
Short answer
Converting an enclosed cargo trailer into a camper, toy hauler or mobile shop costs mainly according to insulation, power and plumbing; a simple camper fit-out is a fraction of a full build with a bathroom and A/C. Check the trailer's axle rating and wall structure before planning heavy additions.

Cargo & toy hauler conversion questions
Can any cargo trailer be converted?
Most enclosed cargo trailers can, but the axle rating, wall structure and height limit what you can add. A builder will check the trailer before quoting a heavy fit-out.
Is a converted cargo trailer road legal as a camper?
Rules on titling and registration differ by state. Ask the builders you are matched with how they handle it in yours.
Is it free to get quotes?
Yes. Builders pay to receive matched requests and we share yours with no more than 4 of them.
