The value of insulation is rapidly becoming apparent. It is currently 32 degrees f outside with 30 mph sustained winds. I haven't started insulating the floor or end caps yet. The walls and rear are getting close. With the small electric radiator I can maintain 65 degrees from the waist up. The first 10 inches off the floor are about 45 degrees. Air temp at the ceiling is about 75.
If I turn on the propane heater buddy it gets too hot to work in about 20 minutes.
I hope my choice of foam panels over spraying doesn't bite me in the ass later with condensation issues. As a test I pulled a panel back to the metal and it was really cold but dry. Within about a minute condensation started to form on the metal.
This was a skin panel that I originally plopped foam against without even bothering to wipe the condensation off originallly, so I was wondering if it would just get wetter or dry out.
Does anyone have long term experience with a foam panel insulates vehicle like this? How did it fare after a few years? I have three inches of polystyrene panel with foil to the outside and inside.
