Why Build a Cargo Trailer?

A cargo trailer conversion gives you something no van can: the ability to separate your living space from your vehicle. Tow it with your truck, SUV, or Jeep — unhitch at camp and you've got both a home base and a free vehicle. You also get significantly more square footage per dollar than any van platform.

Use Your Existing Vehicle

No need to buy a van. Tow the trailer with whatever you already drive — truck, SUV, Jeep. Your tow vehicle stays functional for daily driving when you're not on the road.

More Space, Less Money

A 7x16 cargo trailer gives you roughly the same floor space as a Sprinter 170 Extended — at a fraction of the vehicle cost. That leaves more budget for the build itself.

Detachable Living

Unhitch at the campsite and drive your truck to the trailhead, the store, or wherever you need to go. You can't do that with a van.

Fully Customizable

Trailers start as a blank box with no wheel wells, no cab intrusions, and no factory constraints. The layout possibilities are wide open.
