// Materials

What we will not
substitute

Every one of these costs us more than the common alternative. They are also the six decisions that determine whether a trailer is still square in ten years.

factory-built aluminum

Factory-welded tube steel, hot-dip primed. Not mild steel with a coat of paint, and not a bolted kit frame. It is the single biggest reason our trailers weigh several hundred pounds less than the steel equivalent.

RTP rubber coin flooring

Laid over the sealed factory floor. It takes a dropped engine, a spilled tank of fuel and eleven Californian winters, and it is the single cheapest thing that stops a floor going soft.

Dexter torsion axles

Independent torsion with electric brakes on every wheel. Quieter at seventy than a leaf-spring setup and considerably kinder to whatever you have strapped down inside.

Tinned copper wiring

Marine-grade, labelled end to end, fused and diagrammed. You get the schematic with the keys, which matters when you are three states away on a Saturday.

Powder-coated steel

Every rack, stand and bracket coated in house — in your team colours at no extra cost, because the powder is the powder whatever colour it is.

Closed-cell insulation

Walls and roof as standard, floor on the cold-weather package. It is as much about condensation as about temperature; gear that stays dry lasts longer.

Option pricing is indicative for concept purposes and is confirmed in the written quote before we place the factory order. Anything not on this list is quoted individually — roughly a third of what we build includes something that has never appeared on an option list.
