What it is

A small fabrication shop that builds trailers from steel or aluminum to a customer's spec, such as flatbeds, dump trailers, equipment haulers and livestock trailers. You can also offer a few standard models.

Your first three steps

  1. Visit local farm, contractor and dealer customers to learn what trailers they can't easily buy, and sketch 2 or 3 starter models
  2. Find a rentable shop or industrial unit in your county and check zoning, power and fire code requirements
  3. Price out your equipment (welders, plasma cutter, saws, jigs, lifting gear) and decide what to buy used versus new
Who pays

Farms and ranches, landscapers and contractors, small businesses, and private owners who want something that off-the-shelf dealers don't stock.

How it makes money

A price per trailer, usually with a deposit up front for materials. Extras like ramps, toolboxes, racks and custom paint add to each order.

Skills that help
  • Welding and metal fabrication
  • Reading plans and basic design
  • Quoting jobs and managing customers
Watch out for
  • Trailers are treated as vehicles under federal safety rules, so check NHTSA requirements for manufacturers, labeling and VIN assignment
  • Check your state DMV rules on titling and registering new, custom-built trailers (for example manufacturer's statements of origin)
  • Product liability insurance, since a failed trailer can cause serious injury
  • Welding and metalwork risks, so check fire code, ventilation and workers' compensation once you hire
  • Steel and aluminum prices change, so quote with a buffer and take deposits
  • Startup costs add up quickly: equipment, a shop lease and deposit, insurance and initial materials stock can take most of your budget
