Trailer Builder is worth using when the lot has nothing that fits. You choose the width, the length, how tall it is inside, how the doors work, the rating, and the color. It gets built and you collect it here off I-90, usually six to eight weeks later.
What people change most in this corner of Idaho comes down to two things: distance and winter. A trailer that has to be self-sufficient for a full day at Sandpoint or up the Silver Valley needs more inside it than one working a single town. And anything that will be loaded in February wants a ramp and a door arrangement you can operate in gloves.
- Height inside, so shelves go up the wall and leave the floor clear
- Rating, rear door type, where the side door sits, and the finish
- Vents and lighting, plus a shore inlet if you will work out of it
- Track on the walls, and rings placed for what you actually carry
Underneath it all is the Interstate DuraFrame steel framework, with.024" aluminum siding as standard and.030" if you want it. Nobody else retails Interstate - why Interstate covers what that means for the frame - and about 95% of the finished weight is sourced in the USA.
Stuck on the specification? Tell us the worst load of a normal month, not a typical one. That is the load the trailer has to survive.
