Colder weather camping

jtbuilds, Take a look at the Olympian Catalytic (Amazon, pretty reasonable). Several models, ours is relatively thin (front to back), installed by the original owner. He and his wife did extensive winter camping, and were pleased with it. We just got our class c recently, so can't make a truly informative answer. But, will be testing it very soon on a short "shake-down" cruise to the Bighorns. Ours is mounted, on left side of entrance, beneath the folding kitchen counter extension. This area may not work with your floor plan.

Will include pictures....when I learn how!
