Thanks. Mud flaps on my wish list. Not sure how PPF will protect the backup camera eyes. But I think I found a solution - with a not too expensive tailgate cover I can use just when the gate is down. It straps on and is padded enough to protect. When I have the camper on the bed and towing the horse trailer - will just remove the tailgate, cause I most likely will be on mountain roads with lots of rocks. I've not had a truck that could do it all before - love it.
