The “Wall”....For Those Who Camp in the Cold

This is one of those posts to ignore, if you don’t winter camp. For the select few of us that do....this “may” be of interest.
As we all know the van section of the Motorhome offers near zero insulating value. This area of huge heat losses causes your forced air heat to run more using more propane and “drawing-down” the batteries faster!
It’s merely a “bubble” foil insulation “Wall”,placed between the van cab and the Motorhome living quarters. The “Wall” consists of two sections of “bubble” foil insulation cut to width, and velcro’d together for floor to ceiling height.
The three photos show the separate pieces and the third the two velcro’d together. When placed between the van area and the living area, it should help on those “cold” nights. The only drawback is....when rolled-up oil is rather bulky, taking up space where storage is at a premium. The plus....it weighs nearly nothing!


  • Slightly off-topic but related, I wonder if the external white windshield covers keeps the heat out better then the inside silver heat shield type reflectors.

    The external cover is certainly cheaper !
  • I bet they also help a lot in the summer when it is hot. We noticed a huge difference just putting foam in the skylight and vent of out TT
  • When we owned our Class C we used a set of Thermal Curtains on a length of paracord. The curtains kept the cold (in winter) and the heat (in summer) in the cab area and out of the house. Using the curtains allowed us to access stuff stored in the cab without having to go outside or to completely remove the barrier.

  • Off topic, but when pulling into a camping spot with our Ford V10 Class C, I find a terrific amount of heat of course coming into the cab interior from the large mass of the engine for quite some time.

    In warm/hot weather, I sometimes leave the hood up so the bulk of the engine heat can exit out the open hood instead of into the cab's interior. Even with our isolation curtain put up between the cab and the coach, exiting engine heat this way allows us to cool down the coach interior much faster with fans or the air conditioner.
  • Yes that doghouse continues to radiate heat for quite some time. Its pretty good though for early spring / late fall camping !!
