I purchased a 16SEQ from Amazon. The box was OK but the furnace
must have been dropped because the case was distorted and half of the tack welds were broken so I returned it for a refund. I did notice the inside fan blades were plastic and the blades had a swept design. When I tried to re order the price increased so I'm now planning to go to the Scamp
Factory and maybe just have them install the furnace. I first tried installing a new Atwood Everest furnace I had but since I had a Deluxe it did not fit the existing hole .
The Suburban housing SEQ should be the same size as the SE but the exhaust ports is what I would be concerned about. If you download an install manual the measurements are shown in the manual. Or you could call Suburban or Scamp
to see if it would fit.
