What makes a heated underbelly?
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?
