# Trailer3D

> Trailer3D is a free US marketplace for custom builds on wheels: food trailers, food trucks, camper van conversions, Class C and Class A RVs, and cargo trailer and toy hauler conversions. Buyers design a food trailer or food truck in a free 3D studio (live itemised pricing and code checks) or describe other builds in a short questionnaire, and the request goes to no more than 4 verified builders who build that vehicle type and serve the buyer's area.

Website: https://www.trailer3d.com. Operated by SeedInov Technologies. Serves the United States.

## Key facts

- Free for buyers. No obligation to accept a quote.
- Each request is shared with at most 4 builders, matched by vehicle type and the buyer's ZIP code (the builder's state, neighbouring states, or nationwide, as the builder chooses).
- Builders are verified before they can see buyer contact details: business registration, insurance and recent builds.
- Builders pay for each request they unlock. There is no in-platform messaging: the builder contacts the buyer directly by phone or email.
- Price ranges are what US builders commonly quote, not offers. Last reviewed 2026-11-03.

## Typical prices (USD)

- Food trailers: $60,000 to $150,000+. Build time: 10 to 16 weeks after the design is signed. Sizes: 12 to 34 ft. Typical new custom builds with a full hot line. Coffee and dessert trailers often come in lower; long BBQ rigs higher.
- Food trucks: $100,000 to $350,000. Build time: 4 to 6 months, chassis availability included. Sizes: 12 to 26 ft box. New chassis plus a custom box and kitchen. Refits on a used step van can come in well under $100,000.
- Camper van conversions: $30,000 to $120,000+. Build time: 6 to 16 weeks once your van is at the shop. Sizes: 144 in to 170 in extended. Conversion only, without the van. Electrical, a wet bath and custom cabinetry move the price most.
- Class C RVs: Varies with scope. Build time: Depends on the shop and the scope. Sizes: 21 to 33 ft. A remodel and a new build on a bare chassis are very different jobs. Builders quote once they see your plan.
- Class A RVs: Varies with scope. Build time: Depends on the shop and the scope. Sizes: 29 to 45 ft. Ranges from interior refreshes to full custom coaches. Builders quote after reviewing your plan.
- Cargo trailer & toy hauler conversions: Varies with scope. Build time: Depends on the shop and the scope. Sizes: 12 to 32 ft. Insulation, power and plumbing drive the cost. Builders quote after seeing your plan.
