It really wasn't the squirrels with roaches I was concerned about. There are several other items within the utility basement and underbelly that are of concern. Such as:
1) The Iota Automatic Transfer Switch which was recalled in 2012. (Do you believe Keystone has recovered all of them?) The Iota was responsible for several fires and many near-fires.
2) Improperly placed space heaters in the basement area.
3) Furnaces that malfunction and/or are not properly maintained.
4) Dometic and Norcold gas/electric refrigerators that malfunction and/or are not properly maintained. I know I guy who recently lost his 2008 Mobile Suites from a refrigerator fire.
5) Shore power connections that are not properly torqued that oxidize and overheat.
6) Gas/electric hot water tanks that malfunction and/or are not properly maintained.
And those are just things that come to mind immediately.
I would argue that the foam insulation, as clearly marked, would probably be more flammable than the coroplast, but you are correct in that the harder plastic of the coroplast would be flammable. That's not even mentioning the the toxic gases emitted by combustion. However, the coroplast would hold the flame in the underbelly and probably direct it from the openings front and back along the length of the RV in a type of flammable blast furnace fashion as the foam burned. I saw the unfaced Fiberglass or rock wool as being a non-flammable insulation which also would reduce the amount of oxygen by volume in the underbelly. Besides, the Fiberglass would make a very uncomfortable nest for those smoking squirrels!
