I have finally decided to buy a trailer. I want to be able to haul siding, and at 12’6″ I think a 14 footer is the way to go (i don’t want it any longer than necessary). I have seen some for about $3900,haulmark & doolittle brands. I have also seen some for about $2900 various different brands.  What can you tell me about the difference? is the extra grand worth it? Thanks for your input.
