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.
Excellent point.
We used cargo trailers as tool trailers when I had my small construction company. These trailers were moved in a 8 state area to different construction work sites. My first one was a 7k GVWR trailer with 14" tires. Every trailer I bought with 13"/14" I upgraded to 15" or 16" P tires. I found them to last 35k-45k miles at max axles loads.
I found taller tires roll over obstacles/potholes/curbs/etc easier than shorter tires.
WE learned a lot with this trailer.
As business grew we needed more tool trailers with more robust axle/frames so I moved on up to 10k trailers. Depending on trailer brands I looked at they come with Dexter or Rockwell American axles. The 10k trailers had cross members on 16" centers/heavier flooring/more sidewall studs/etc.
When looking at the different trailer brands and sizes go under and check out frames/axle sizes (brakes)/cross members/out riggers and sidewall framing construction. There is a difference.
And don't forget brands can be marketed in one area of our country and not in another.
