We have an enclosed and insulated underbelly in our travel trailer. The factory literature says it has a heated and enclosed underbelly.

Do they call it a heated underbelly simply because it happens to have a few short runs of furnace ducting under the floor (furnace is centralized)? Or do they run some additional lengths of furnace ducting underneath to distribute the heating more evenly throughout?

I am also thinking that if a bit of furnace ducting under the floor is all there is, it won't do much from preventing freezing of the tanks in cold weather?

Our DSDP has a hose with a blower on it that directs heat to the storage bays when the furnace runs. I do have a separate switch so the blower doesn't run in cool but not cold weather.

Mine has heating pads similar to radiant flooring. Haven't had the chance to try them out yet.

My Big Horn has a vent hose coming off the furnace that drops down into the area below the floor and above the underbelly mat. There is also insulation on top of the under bell mat.

If I was going to use it in the winter I would be using a ceramic heater in the storage bay plugged into a thermal cube so it would turn it on at around 32 degrees and off at 45 degrees.

Your trailer, like mine, has a few feet of flex hose pushing heated air from the furnace into the tank area. The air then is expelled out thru the leaks in the belly cover. It is a very inefficient system.

On our rig the heated air vents are standard, the heat pads were an option that I didn't get, but that was because we bought it to go full timing in warmer areas and that hasn't happened yet!
