Hart, I understand what you are saying about the crap tape that holds this on. When i had the 03, they used to pop of from time to time. Go buy some 3M tape and fix it yourself. The dealer wil just give you ulcers.
I had to make holes for my SUT guards to go on. They use some type of rubber bushing that expands when you tighten up the screw. It'ss take a heafty branch to knock that out. And i think if that ever did happen it would pop the gromitt without ruinging the body... the branch would do that. Make sure to clean the surface of the brush gard and the truck body before installing the new tape.
