Don't they sell just the plastic cover separately? I could swear that I've seen them at Camping World.

I believe that ours were the clamp-in type (it's been a while). I'm a little afraid of really strong adhesives, if you need to take it of for some reason, will you be able to? Are the risers in good shape? If not then I'd think about replacing them, just in case.

Not a fun job, I have one more to do and really don't want to do all of that scraping of the caulk. Maybe if it cools off and I have a free weekend I'll go at it. If you put screws in, caulk goes a long way towards keeping the leaks away.
