I bought a trailer from Wholesale Trailers and the customer service was good.
I decided to get a 6x4 high sided black trailer.
Looks very sturdy however it seems to be covered in a thin layer of paint on the top base of it. Within a few days there were rust marks even though it was tilted and dried right after rain.

I did pay just $600 for it prior to blue slip but I expected it to be protected a bit longer than a few days. Not big rust areas - just small circles. Have hardly used it but plan to in the future.

I would have liked to have been told it has one coat of paint on the base floor.
