I rebuilt my steps this winter, and had the old "steps" completely removed. The furnace is in no manner, way, shape or form ducted to those grilles on your steps. I determined they are there as a 'forced' return. Meaning when the furnace comes on it is forcing air into the living space, depending on how long the furnace runs the possibility exists to pressurize the trailer and reduce the efficiency of the furnace fan. That said you can accomplish the same thing as those grilles by opening a window. The way these rigs are constructed the furnace will draw from outside and the basement area LONG before it pulls any from the cabin.
ALSO the grilles are the same size in every trailer they make, so every set of steps are 50% complete (the way they build) so it's also a time thing. They can face the steps with 6 pieces of pre-finished pre-cut 'wood'. Therefore removing the need for a carpenter.
