A $3k trailer is just that...it will pull and keep stuff covered, but I wouldn't be putting a bunch of heavy point load items in there.
Shows lack of reality here.
All trailers will have the same axles, who are manufactured in only couple locations in US. All of them will have the same door latches, hinges, vents and door locks.
All trailers will have strong frame as steel is cheap and no manufacturer will take chances with structural undersized.
What cheaper trailer will have are thinner outside sheeting, less inside ties and probably some poorly torqued screws.
I drove my 5000 lb convertible inside $3000 trailer just fine. Enough said.
My impression is that trailers are build by the same labor TC are.
Whatever farm-boy is available in the area - he's got the job.
