I have a 2004 King of the road and there is a 2" wide rubber "bumper" about a foot up from the bottom of the camper. The caulk is pealing above and below the "bumper" and it is leaking on the wood behind the fiberglass. What is the best way to fix this? I would image to be done right the bottom 1' would need to be removed and the wood replaced behind it. Any suggestions?
