We had one incidence of the ESC (factory fitted) operating, that I know of, on the way back home from picking up the WnP in Adelaide. We missed a turn-off and were then committed to a narrow, windy & rough few K's were there was no possibility of turning around. On one corner the van brakes most definitely locked up momentarily. Both hands were rather occupied at the time, and my mind, and I can't see that there was any possibility in that circumstance were I would have been able to have manually operated the controller without an extreme extension to a 3rd appendage. In hindsight it was one situation where the ESC probably should have been disconnected prior to entering that road but it has made me more aware of some road conditions where it should be disabled and I'm glad that I had rewired the power feed via a 2nd Anderson plug. Having it wired the Jayco way via the 12 pin connector doesn't make sense, especially when they had it going via the smaller pins.
