In addition to the foil on the rear windows, I used odd bits of air bubble packing stuffed behind the vans closed blinds, which I think worked really well as there was no condensation on the these windows at all.Tim
Great info. I was originally borrowing a friends roof topper, but decided it was to bulky. So have bought two rolls of silver foil insulation on Saturday. I am thinking of wrapping around the outside of the poptop for a bit of extra insulation. Never thought about using it to insulate the rear windows. I might do that.
Do you not have a diesel heater...?
Plan to use this for an hour at bedtime, then again an hour before waking up.
Only used the diesel heater just the once as we arrived at campsite when it was closed (1:00am). The temp on arrival was -10c but it did keep us warm too. Setting 3 I think. Once on site the elec. heater worked fine and charges were a per day rate rather than unit use, so made sense to stick with the electric.
