I'm very happy with my choice of going with the cheap heat system. Please look into it. It's sold by rvcomfortsystem.com, check it out. This system hooks up to your gas heater unit and gives it the option to heat electric or gas. All the portable electric heaters don't heat the under belly of your camper. I have been using my camper for three years with the cheap heat system and been very happy with it. I no longer use the gas side of my heater to heat my camper. This system works just like the dealer claims. I can tell you that this system works and I. For one would not go back to using portable electric heaters. Please keep an open mind and look into this system.
