I have been using the Demco solid deflector that mounts on the tow bar and also had the IBC splash stop guard on the trip to Alaska. The IBC unit was too low and I think it was to blame for the CRV becoming so filthy in spite of washing it every chance I had during the trip.
Since this is a new MH, I am probably going to order the smart solutions rock solid unit at http://www.amazon.com/Smart-Solution...=rv+rock+guard
although I have heard a lot of good things about the Blue Ox unit that GJones is using. If I knew that I could adapt the Blue Ox unit to my Demco tow bar, I might try installing it on mine.
I camped next to a Class A in Valdez that was towing a CRV and the front end was being held together with duct tape. The windsheld was cracked in several places, all headlights and fog lights were damaged, and the rest of the car was going to have to be refinished. All due to the solid rock guard being mounted too close to the ground and kicking up gravel and stones, so I am just a little leery of them. The owner said that once someone pointed out the problem, he suffered no more damage after raising the guard to the recommended 4" height above the ground. Of course, by then it was probably too late to see any new damage.
