You're not replacing 1000 cfm of air ... you are drawing supply air from inside the camper, warming it, and then just blowing it right back inside. The combustion air is totally separate on the outside of your camper. What my link shows is that the back wall of your front storage compartment does not completely seal off the area your furnace draws from. There is open space between each floor joist and open space straight down into the belly pan which is by no means 100% sealed tight from the outside air.

It's obviously you know what you're talking about. I just don't see how with your vents under the steps sealed off you are drawing air from inside the camper. What am I missing.
I have taken rigid insulation board and with duct tape tried to seal between floor joists. Not 100% sealed but I think better.
I value your comments as I have read many.
