Country Coach and Featherlight basement air should not be confused with Cruise Airs...
While the original basement air is no longer being made, Coleman makes a replacement that works fine with little modifications. Donnie Myers and others have had great success rebuilding the old units, so that is a good option too. You do loose one of the partial bays on each side but they are not full across bays (I believe the fuel tank is in the middle). We are very fond of our basement airs in our 2006 Country Coach.
