If I remember correctly (and yes that is always a question), the Tradition is a downsize from the Select Suites and is pretty much a competitor for the Redwood. I just looked at the information on the frames and the Tradition has a 12" I-beam frame. On the Redwood, they mention that the "drop frame" is 10" and the "main frame" is 12".
So, is the "drop frame" that part that the majority of the coach is built upon and that the suspension is attached to, with the higher part of the frame being for the bedroom? If so, then I would worry a bit about that 10" drop frame.
Oh, and if you consider a used Mobile Suites or Elite Suites, look at the website of Rolling Retreats in Elk City, OK. While they are a full DRV dealer, they occasionally get used units and resell them.
