Perhaps you should consider RV driving lessons to help you avoid the need to protect your coach from hitting curbs and cones? Most owners travel for years without that problem. The simple rock guards might be worth it if you expect to drive on gravel roads a lot at moderate to high speeds.
Yeah yeah yeah. Most owners travel for years etc, etc, etc. Sure they do. And some like me are traveling thru a construction area with a line of traffic cones on one side and a six inch drop off on the other side with oncoming cars in that lane, when the trailer in front of me clipped a cone and caused it to spin out of line and into my lane.
I had no place to go except straight ahead and hope I missed the cone. I didn't. Stopping was not an option. It dented the surface a tiny amount and smeared it with "cone guts". It could just as easily have been any kind of road debris kicked into my lane by a passing vehicle. So what would you have done? I'm not a rookie truck driver but I am a new RV driver. Maybe there was a better option that I didn't know at the time? So what would you have done?
I want to install these plates as sacrificial coverings. Two pieces will cost me under a hundred dollars and an evening watching TV while cutting them out with the shop shears. They'll save my coach from minor damage caused by unavoidable contact with road debris. Yeah yeah most owners can and will avoid that debris but some of us will hit the stuff that's unavoidable. Will RV driving lessons teach me how to avoid unavoidable stuff?
Sooner or later it will happen to everyone. It happened to me sooner than later. I'm just trying to mitigate any minor damage from next time.
