Your pics do not show this. Do you have FLOOR heat vents. These would be cut out in the floor. Remember, the 3 or 4 duct rule is not valid if you also have the floor cut out that routes some of the air thru the floor cavity. The furnace sits on top of this additional duct. You need to post the MODEL number of your RV and the Model number of the furnace. Doug
PS, If the pics are of your furnace you have 4 cut outs for 4 inch duct work. Only 2 are being used. ALL the Suburbans have up to 5 duct plates. That way, there is a duct available depending on how the furnace is mounted. The OEM decides which duct plate holes to use.
