Our previous coach (2008 Monaco Dynasty) had the mud-flaps behind the rear tires and the hanging guard about halfway between the rear wheels and the rear of the coach. We got a lot of stone chips without a cover on the tow car including a broken windshield and broken fog light on the '07 Honda CR-V. I had everything fixed and then looked for protection.
So, we bought a front cover for the car and that cured anymore damage. Our new coach has a flap at the very rear of the coach that is not hanging on chains like the previous coach, it's more stationary and rigid. I don't use a cover now on the '13 Honda CR-V and no problems.
After several years of using the car cover, it did get tiring keeping it clean of debris. I am enjoying not having to worry about that car cover. But, I would use it if we were at risk of damage like before.
