I have a 2017 Cougar 341-RKI fifth wheel with the same under stairs vents. I was losing a great deal of a/c capacity cooling the front storage area. I simply closed them off with the solar window insulation. Wow...what a difference. Also, I decided to try it with the furnace on and it works fine. There apparently is sufficient fresh air entering the furnace area of the coach not to affect the furnace performance. However, when temps get well below freezing, I would open the vents up, since that is how the front compartment pipes receive their heat. Give it a try!
