We do the same as SkiGramp, slide in, blanket over bedroom windows, blanket over dash.
We have also put a blanket across the front cab area holding to cabinets. We can still see the tv, but it really helps. The cabs are so poorly insulated.
Also we have put little box heaters in the cargo bay. It really helps on the floors.
We also have heated mattress pads on the bed. We can turn the heat way down and that really helps at night.
