I have a 2003 coachman. I would not buy anything else but thats me.. Mine is 2003..
I like aluminum sides. I have seen too many bonded sides delaminate and have issues.
If your looking at those models do your self a favore. Get the opposing couch and dinette. You will not regret it.
Mine is a rear bath front queen with opposing couch and dinette..
I recommend you look at this model.
