I drove that mountain before towing my 5ver. It is steep and winding. However, I think the problem is not the road but the driver. There are a lot of drivers out there that shouldn't be driving RVs. Surprised some even have a drivers license. I have been in RV parks where everthing is flat, and they still run into things. I just hope that when I lose my skills, maybe because of age, I'll be able to realize my limitations. All that said, accidents do happen. Even the best and careful drivers run into problems. Sometimes mechanical reasons, Sometimes sucked into accidents due to mistakes of other drivers. JMHO
