Jim,

I do not have this on my coach, but I have seen a number of coaches that have them, few of which have the shield in an unbent condition.

If I had one on my coach I would likely remove it and use it as a template to make a replacement from heavy rubber such as mud flap material. Replacing it will not prevent it from getting damaged the first time you pull out of a steep driveway or have to back your rear end over a parking bumper.

Just my $.02.

BTW, it is a critical part of the coach and is intended to maintain a separation between the cool air pulled through the radiator and the hot air exhausted by the fan so it should not be left off or bent so its purpose is defeated.
