I can't see any advantage the truck window cover would have over the HeatSheet or foe that matter the cheap WM space blanket. Wouldn't they all serve the same as a vapor barrier and/or reflective blanket? Although perhaps the wind shield device has some ccf type insulation properties, not sure, but I'm also not sure if it would have enough flexibility to work well on top of the pad?
Also, SS users, in way cold temps, don't forget something called a Garlingtor Insulator! ( see new thread, or do a search)
