Like Pete said, the Buddy Heater seems like the unit of choice among many of the FGRV'ers on this forum. That being said, I bought one and seldom use it as an alternative to the main furnace
. The two best things about the forced air furnace
1. It has a nice accurate thermostat so you can set it to your actual comfort zone. With the Buddy, I am constantly turning it up, down, on or off to regulate the heat in the trailer. When I owned a Casita
, I had the same issue with the electric heat strip and with other electric heating devices.
2. The furnace runs on outside fresh air which prevents condensation and doesn't reduce the oxygen
level or increase the carbon monoxide level. I have never felt comfortable going to sleep with the Buddy heater turned on. When it is on, the windows
are totally steamed up at all times.
I have used an RV gas furnace everywhere from Florida to Alaska. I don't know where you could live in the USA that it NEVER gets cold at night. Even in mid-summer, if you go to high elevation it can get downright cool.
I have to admit, the noise level on my Casita
furnace was pretty annoying. And it does quickly draw down the battery
if you are boondocking
. That is the main reason I tried the Buddy. Now I just keep the battery
maintained with solar
panels or an occasional charge-up with a Honda 2000. The Bigfoot
furnace is further from the bed and doesn't wake us up like the Casita furnace, anyway.
