Rock Protection for Toad?

It really depends on where you are traveling. When I went to Alaska in 2006 I was concerned about rock damage and made a protect a tow type guard from an old trampoline mat. This protected the car from rocks coming up from underneath. For the windshield I had some nylon foam material about 1/8 in thick and bonded 1 in thick bubble wrap that would absorb the impact of a stone(bubble wrap against the windshield). It was held in place by closing both doors. From my experience driving miles of dirt roads you are more apt to get wind shield damage from an oncoming car or truck than any thing else. My vents in front of the wipers on the car were filled with small stones so the wind shield cover worked well. I also made head light and grill covers to protect lights and radiator also. My conclusion is the windshield cover was a necessity on dirt roads but on regular paved roads I don't bother. The only real damage I got was a crack windshield on the MH from an oncoming truck on a paved Hi way. I don't now how to protect against that.
