I had towed the Cherokee for a few miles when the install was first completed, but it's first true test was the 400 mile trip to NC. All I can say is that it all worked as advertised.
The only time I felt the Cherokee was when to tow bar arms initially locked in. She tracked well. She seemed to track with or slightly outside the coach. There was no slop in the hitch. I figured that would be the case, as when I originally installed the tow bar, it took me quite a bit of maneuvering to even get the thing in the receiver. to say it's a tight fit, is putting it mildly. The RVibrake worked as advertised.
The only issue that I had was with the TPMS sensors on the Jeep. The monitor in the coach lost the signal from a couple of the sensors, and the monitor beeped to let me know. and beeped, and beeped... I found if I turned it off and then back on, it was fine, until later it would get a signal and then lose it, and beep again.
The TST signal repeater that I ordered on arriving here is waiting for me when we get home. Hopefully, that will correct that problem.
It's good, when it works the way you planned!
Thanks all, for your opinions and suggestions. It helped me making some tough decisions.
