We stopped at a roadside strawberry stand to buy some produce (on our way home from Yosemite). When we started the engine on our Class A motorhome, the coach wouldn't move. The Auto Park Brake system had locked up the parking brake. Given that it was Sunday, not many places were open. We were only a mile from Manteca RV...a giant RV sales dealer. I asked them if they could take a look at the problem, and they said "We only work on coaches, not drive trains, brakes or transmissions."
I asked if they recommended anyone who could work on our rig, and they said "Monkey's". We ended up staying on the side of the road overnight and called Monkey's when they opened on Monday. After getting towed into the shop, we talked to the owner and head mechanic David. We got an estimate and proceeded to wait. David is a man of few words, but he knows his stuff. After getting two parts deliveries and working on it a few hours, we were back on the road. His price was reasonable for the amount of work he did and we were very happy with the service. Highly recommended. They work on autos and RV's. The problem with our J71 auto park brake system was a faulty neutral safety switch unit and a faulty pump relay.
