Build a Custom Cargo Trailer in Phoenix, AZ

Build the trailer the work actually needs. Width, length, interior height, doors, GVWR, and color are all specified by you, with collection here in roughly six to eight weeks.

In this market two specs get revised upward more than any others. Interior height, because shelving that climbs the wall leaves the floor usable. And ventilation, because an unvented metal box in July is not somewhere anyone will work, and heat is hard on whatever is stored inside it.

  • Roof vents - specify more than seems necessary
  • Interior height, and shelving depth to match
  • GVWR, rear door style, side door placement, exterior color
  • Wall track and tie-down points positioned for the real load

Every build uses Interstate’s DuraFrame steel framework with.024" aluminum siding standard and.030" available - steel frame, aluminum skin, and about 95% of the weight sourced in the USA. TrailersPlus is the only retail seller of Interstate; why Interstate has the detail.

Builds run on proven standard configurations rather than one-off engineering, which is what keeps quality consistent and the lead time honest.
