Installed in the Spring and working well to keep the wife and kids warm at night. Was a great purchase to keep them comfy. Bought it from Rocky Mountain Westy up in Fort Collins which is now found at VanCafe.com--$750ish. Shipped to the house same day I bought it and was here in a few days. I bought the propane bottles from homedepot.com with ship to home option. ~$125 for two 11# bottles.
