Used the BB for over 40K miles and never had a problem with the BB. I did once make the BB adjustment (seat) to tight. Having towed the Cobalt for 35K miles by this time, I could feel something was not right with the TOAD. The MH typically does not even know the TOAD is there, its that easy of a tow. Felt this three or four times at stop lights in town. Pull over to a HD and checked the TOAD. Could smell that the brakes were dragging, not on all the way. Checked the brake lights - not on. Re-adjusted the BB and the problem went away. No noticable damage to the brakes. I do have an LED on my dash that tells when the BB is applied, not from my brake lights. I also use the microphone in the rear view camera when first starting out to listen to the TOAD. I can hear a lot of things, like if the front wheels aren't turning, but this time it was an unexpected tugging by the Cobalt on the MH. Situational awareness is important. JM2¢...
