I ended up going with the Dicor non-leveling sealer. The local RV dealer actually had it for cheaper than I could find in on the internet????? When I picked it up the counter person told me "Just go with the silicon, that is the only thing we use around her". I went with the diroc!
Thanks for the tip on the Butyl rubber. I picked up a roll of that too and it seems like it could take care of the sealing needs all by itself... I used Dicor anyway.
The Cover on the electrical umbilical cord is broken. I don't want to provide any unnecessary gaps for mice to get in. I am thinking of replacing the cord cover with a flush mount plug. I haven't found a good flush mount plug yet though. My umbilical cover is 5 1/4" round at the extents of the flange. Any recommendations for an affordable cord to flush mount plug conversion?
