I'm looking at 6'x14' trailers and am down to either Continental Cargo(with Northwest package) or Haulmark (Haulmark transport dlx). Haulmark is about $700 less, but is basically lacking the floor vents and all but the front stonegaurds. My main issue with Continental is the inside walls are wood, I can imagine them getting damaged in no time. Not sure which would be a better buy. I really know little bout CC, haven't noticed any around. Any suggestions? Any idea how good 'floor through vents' are?
