They probably buy truck loads of supplies and have illegals put them together for $5 an hour.
Good luck, We've tried several different brands/models for our semi trailers. If they're sealed up tight enough not to leak the condensation builds up and stuff inside still gets ruined.:doh:I've been needing to get new boxes for my truck too. I'm the same way though. I don't want to turn loose of the money and I want to make sure I get some that are not going to leak a year from now.
