Electric Fireplace or AC/Heat pump

Replace an AC, cost point is a bit hard to go up against. A dead AC maybe but not a working unit. The electric fireplace doesn't take up much space and look nice if you have a place to install but you can buy several small space heaters for the same price that are not fix in one place. I went thru the same coin toss and ended up with two space heaters. Next coach will have heat pumps but not the current one.

If you winter camp don't rely solely on electric. Many rigs have a duct off the propane furnace to the wet areas (fresh and waste tanks)under the floor to keep vital stuff from freezing.
