Hi: I have two questions. After looking into a few Edge RVs for sale, I noted that the model number and length seem relative for the shorter models; but the M22 is stated as 26'. It doesn't seem in keeping with the other model numbers and their lengths. Could you confirm if the info I have is correct. If so, why the confusing model number? Also, why did Heartland stop using the European windows? I am worried they may have problems such as losing tightness, breaking in winds, coming open while driving, or losing their clarity. Before we purchase one Edge or another, I would appreciate any insights from the manufacturer and from other Edge users. Thanks so much; the Edge looks like a very nice trailer.
