Your shell is ordered from the factory to your spec. What happens after it lands in Napa is ours: five to ten days in a bay, depending on how much you asked for.
Not a marketing timeline. This is what happens to your trailer between the day it lands in Napa and the day you tow it away.
Your shell arrives from the factory built to the spec you signed off. First thing we do is go over it: every seam, every light, every latch, the floor, the ramp springs. Factory trailers are good but they are built fast, and it is far easier to sort a sticking lock now than with a tool wall bolted in front of it.
Anything wrong at this stage is the factory’s problem, not yours. We deal with them, not you.
Racks, stands, brackets and the bench frame are cut, welded and powder-coated on our own bench, off the trailer. The cut list comes straight from the drawing you approved, so there is no step where somebody’s reading of “about four feet” becomes a problem.
Building this off the trailer rather than inside it is slower to set up and considerably more accurate — which is the whole point of the exercise.
Wall and ceiling panels, insulation if you specified it, and the rubber coin floor laid over the sealed factory ply. Then the tool wall goes up, on the side opposite your door so you are not walking round a kart to reach a socket.
This is the week you are most welcome to drive up. Plenty of people move something twelve inches at this stage, and that is exactly what we are for.
Kart stands set to your chassis height, tire racks to your compound, engine bench at the height you actually work at rather than a catalogue number, cabinets, fuel station, chocks. The part that turns a cargo box into a race trailer.
Every stand and rack is powder-coated in your team colours at no extra cost. The powder is the powder whatever colour it is.
12V and 110V looms, labelled end to end, fused and diagrammed. Shore power gets tested under real load rather than just checked for continuity, because a 50A inlet that reads fine on a multimeter can still trip with a compressor running.
You leave with the schematic. That matters if you are three states away and something needs attention on a Saturday.
We walk the whole trailer together in the shop. Every latch, every circuit, every strap point, the factory warranty paperwork and ours. Then you get the schematic, the keys, and you tow it home.
Factory warranty on the shell, ours on everything we fitted. If something we built needs attention, it comes back to Napa.
They are not, really. The actual metalwork on a race trailer is not a six-month job for anybody, including them. What takes six months is the queue.
A national manufacturer schedules four hundred units through a single production line. When you place an order you are not waiting for your trailer to be built — you are waiting for three hundred and eleven other trailers to be built first. Almost none of that time is work on your unit.
We sell slots instead of positions in a queue. There is a fixed number each month, and when you take one, your trailer occupies a bay from the day it lands until the final walk-through. Nothing displaces it. That is the whole trick, and it is why we cannot simply scale up without becoming the thing we are trying not to be.
Honesty requires the other side of this. We build a small number of trailers a year. If all the slots for a month are taken, you wait for the next month — and in a busy season that can be six or eight weeks before your shell even ships. We will always tell you the real date on the first call rather than after the deposit.

Tell us how you race and we’ll come back within one business day with a layout drawing and a fixed price.
