Well, Guess I'll pipe in again!
Flat towing is the BEST way! My 2 was the FIRST towed (prototype) for the roadMaster set up! I haven't read the link yet but I can Guarantee it was the RV/towed H2's fault!!
They most likely Didn't have a Brakeaway Installed OR A BRAKING SYSTEM!
Their's a LOT of ****Heads out there that that don't have the proper set-ups!
