Suburban furnace in 2006 Georgetown

We purchased a 2006 Georgetown 2 months ago. When we used the furnace very little air and heat came out the floor vents. I removed grill and cover and found no path for blower fan to move air to the floor cut out vent. Has anyone else had this problem and if so how have you fixed it? The furnace is a Suburban SF35. In advance thanks for any help . Rich

It seems strange that someone wouldn't have already found that on a unit that age.
Was the furnace recently replaced, or was some other work (i.e. floor replacement) done in that area?

The problem is the only way the fan air can get past the heat exchanger is a total of 10 square inches, 1/2" to 1/8" on each side. We figure the previous owners never used the furnace since everything is like new in the RV. It has only 9,000miles. If the round ducts were used there would be plenty of air flow past the air exchanger but the aren't. It only has underfloor vents.
