Is there a shield/guard made to protect the cooler in the front of the tunnel on this sled? There is a few dings and nicks in mine already, it is new, and I dont want to fork out the dough to replace it. I think some of the nicks may be from the studs, but i'm not sure, could be from debris. I'd like to add a guard if possible so I can avoid serious damage to it. Or am I just being paranoid and worrisome about my new toy?
