Re: Insulating question
At Christmas we stayed in the bus,I have back 12ft partitioned off.
One 1500watt heater kept it at 51* and outside was 12*, front of bus was damn cold...as in lick the window...tongue stuck!
So partitions to make space smaller is also key, insulation helps with not loosing/gaining heat or cold.....if you leave anything w/o a heat/cool source long enough it will be same temp as environment
