What's Behind Your Closets?

[Jean-Louis Bourdon]

Hi
having van insulated and carpeted soon

what is behind your utility (fridge/hob/oven) part of the furniture? same carpeting and insulation? or some heat reflective material? other
I read that fridges should essentially touch the body work (it could make some sense but really?)
my fridge will be only electric (1 or 2 way, not gas)
I also plan to have one of these small grill/oven

picts welcome

thanks
