, I have already done the silcone on the back-up cable on our 2010 PC2350. I also found it washing the MH last week.
About 1/2 hour ago I noticed the heat in the two cabinets. I was thinking about looking for a vent to put at the top on the inside to let the heat escape into the coach. Did you figure out what type of insulation and how to put it up in those wierd shaped cabinets?
