I would like to convert a compact van (nissan NV200). I would insulate the roof and possibly one side (likely the side my bed will be on). Does anyone have any experience with partial vs full insulation? I am worried about moisture and condensation and problems that might cause, so I am not likely to insulate all sides. I may be in colder weather somewhat often. If you have done partial insulation- how did you decide which side to do and why? Would you use a different method/type of insulation for the ceiling vs the sides? Did anyone decide not to insulate at all due to potential mold/moisture?
