Went to lowes.
They set the bar pretty low.
$900 gets you a 2000lb 5'x8' trailer with a box frame made out of what I would call "bed frame angle iron". I guess they are depending on the wood decking to be part of the structure. Nothing wrong with that, till the wood gets old and rotted.
Welds are clearly from a stick machine using a small rod with the amps cranked way up and leave something to be desired.

Looked up the trailer laws for New mexico, they give me a lot of room to work with.

If I copy the basic lay out of my rebuilt northern tool trailer with 2 brake lights, 2 amber running lights, license plate light, rear reflector, safety chains, 2500lb cap. with nonbrake hubs the design will be accepted almost every where.

Here are some pics:
(the small trailer is missing a cross brace, need to drag out the plasma cutter and cut a length of that heavy angle iron to fit, and I'm going to cut 2 or 3 extras when I do)
