Heat Return Air

Is there any defined return air path from the basement back to the furnace ?

Mine is a 1998, so it may be set up different than yours, but there is no return air from the basement.  The furnace on mine is under the kitchen counter and pulls air through the ventilation grills in the toekick area.  No air duct is connected to these ventilation grills going back to the furnace and the furnace has no air filter on it to take the dust or dirt from the intake. 

I doubt you would want to cut any sort of unsealed hole going from the basement to the upstairs either.  Having spent the last winter in extremely windy North Dakota, the basement is not sealed up very well (despite my attempts to make it so) and you don't want that cold breeze coming into the upstairs.

Mine has a filter on the return air grill under the refer, but not having a defined return air from the basement means that any air you furnace takes from the living area and sends to the basement is made up by bringing air back into the living area....By leakage from somewhere. This could be direct from outside, which could mean less warm air circulating in the basement, or drawing makeup air direct from the outside, not very good for efficiency.

Wow ND in the winter !

Our Foretravels are not sealed up incredibly tightly like a house would be.  I don't notice it most of the time but when it hits -20F along with a 25mph wind, you become very aware of any air leaks.  Heated tile floors helped this winter with maintaining a more even temperature throughout and most of all, it was a very very mild winter.  Thankfully we didn't get hit with the terribleness of two winters ago.

The old window seals on the Motion windows let a decent amount of air in.  There is no way to completely seal up the area where the water hose and electric cord enter the coach.  The roof fan vent cover doesn't seal up terribly tightly.  Same goes for minor air leaks around the refrigerator.  If you still have the original air conditioners, the seams around the metal blower box cover let in quite a bit of outside air unless you seal them up with duct mastic.
