Howdy ya'll, I do a lot of camping with my 80 and sleep inside. I love snow camping but the cabin is horrible at retaining heat. I have a butane heater but once it's off it gets cold quickly. Does anyone have any tips on modifications I can do/parts to look into replacing to help contain some heat better? Weather stripping? Add some dynamat? I'm sleeping on a platform/drawer setup that is level with the 2nd row seats when folded if that matters. Interior is stock besides that, still have carpet etc. Any insight is appreciated.
