Custom built, Welded box steel and aluminum checker plate construction. very solid, I'd say it's overbuilt but still quite light. Integral aluminum ramps included, Lights all work. My reggy has just expired so you'd have to transfer it to your insurance to take it home. The trailer tires are tall so it has good ground clearance, leaf sprung solid axle, and 1 7/8 ball. It has a fairly long tongue so it tows well and backs very well. The usable deck space is 5 x 8. There is space for more gear up front or to bolt on a gear box. The trailer is a U built. And my pal that made it had a gvw of 454 kg. Assigned to it, not sure how accurate that is though.
