Ok, I took the round bar WDH back. I just couldn't get it set right. E-trailer was great to work with. I took the rig to the truck scales and weighed everything. When the trailer is loaded with two bikes, and the forward tanks are full, the trailer weighs in at 5100lbs with a tongue weight of 600lbs. (just under 12%). Completely empty the trailer weighs 3940lbs with a 660lb tongue weight. (nearly 17%). That may explain the rough ride I expirienced on the unloaded trip through Indiana. I am looking into an Anderson WDH. More to come.
