The only thing I dislike about my Weatherguard box is I can only open it from the drivers side. But I can't knock the box to much since I got it for free. It carries alot of junk (fluids, jack, tie down straps, etc. ). It has taken some pretty good abuse too (haybles falling on it, jack knifeing the gooseneck against the lid, and backing into the gooseneck hitch).
I did have a Delta before this one but it was a big pile of junk. Latches were always screwed up and wouldn't close right.
