How we source prices
Every price on this site is either a typical range for a vehicle type or a live estimate for your exact design. Here is where each comes from.
Last reviewed
Typical ranges in our guides
The ranges on our vehicle pages summarise what US builders commonly publish and quote for new custom builds of that type. They describe a typical spread, not the cheapest or most expensive possible build, and they are reviewed at least every quarter. The review date is shown on each page.
Once enough quotes have been made through Trailer3D, these ranges will be based on those quotes, and each page will say how many quotes and which months the figures cover.
Live estimates in the 3D studio
The studio adds up a priced line for every option you choose: shell, chassis, windows, systems, finishes and each piece of equipment. Line prices come from a builder's parts list. Engineering review usually moves a final quote by 3 to 5 percent, and delivery is quoted separately.
Limits
Prices change with materials, chassis supply and region. A builder's written quote is the only binding price. Where we have no reliable figures, as for many RV and cargo-trailer projects, we say so instead of publishing a number.
