New to the forum and looking at getting an Edge M21. For the factory: Is it possible to replace the roof air conditioner and put a "Cool Cat" heat pump maybe under the refridge or somewhere, to give lower height clearance? Just a thought, if it would be possible. You have the same windows as the T@B/T@DA (love that!) You have done everything right on the EDGE. Now we get into the "What if's" ? The 'Cool Cat' maybe a little heavier but I would be willing to sacrifice a little weight for height. Thank you Ken
