if the booster was in the ducting to the basement, then it would draw from the coach air into the basement. put a 40 degree thermo switch and it would cycle very little....

My mistake, poor choice of words. Trying to keep things a little simple here for those that do not have any HVAC experience. KISS, shall we call it a furnace chamber? What dust doesn't get burned up, and there will be some, will eventually require the furnace to be cleaned. Unfortunately this is not a 15 minute job on these units.

Easiest thing to do is run the furnace built into the trailer on night when freeze is possible. Propane does not cost that much. If you are trying to camp in sub zero temps that is only practical thing to do. We run our fireplace while awake and set the furnace for 65 degrees at night.

The booster does not need to be placed in to the duct to draw air from the trailer. The fan can be controlled by a thermostat that could be dropped into the underbelly of the trailer so it would only run when needed.

Does anyone know if there is a duct vent located in the underbelly or is that area heated just by the uninsulated duct itself?

Yes that probably is the easiest thing to do. However, if you put a booster fan to blow into the underbelly controlled by a thermostat you could just run the fireplace and never have to turn on your furnace unless it got very cold. If he gets down around zero it's getting time to winterize the trailer and stay home. However for some people their trailer is their home.

edit...it would draw ambient air from the coach through the furnace housing, the ductwork is already there, and it would not interfere with normal furnace operation...

ok..why not go into the basement duct??

IF you have one and IF you can get to it then that would work. I am going to have to call FR to find out I guess. I really don't feel like tearing my underbelly apart to look.

What I am saying is you don't need to cut your duct work to add heat to the underbelly. I want to put heat there when running an electric heater. Going into the duct work would not be the best option if the furnace is not running.

If it gets near zero I agree running the furnace will probably be needed. If it is around thirty or forty then I want to use an electric heater if I am already paying for shorepower.

But I don't know if I have a winter package. Again another phone call to forest River I guess.

I was just out looking at the water pump and notice something I didn't see before. There is a section about 6 feet long of flexible ductwork which goes to a register in the bed area. This section of duct work runs are crossed the trailer and is run next to the water lines going to the bathroom sink. I'm guessing that's how they are keeping those lines from freezing.

It is also the reason why so many people complain about the heat in the bedroom area. If that was an insulated duct they would get much more heat in the bedroom. To me it doesn't matter I like a cool bedroom. That's probably the reason they did it because most people do.

you could just trace each line from the furnace to see where it goes.. usually the basement line restricts to 2" but not always.
