You and your better half need to figure out just what you need, and what your plans are. If it's just the two of you and no plans to have guests with you, than you might not need a cab-over bunk. Look at the Forrest River Lexington's, Winnie Aspect, Coachman Concord or similar units. They'll have front entertainment centers, a seamless fiberglass front cap, and usually a one piace fiberglass roof which will eliminate most of the leak problems.
Guests, kids or grandkids, your probably going to need a cab-over bunk.
If your planning on long trips, slide-outs will give you extra room for those days your stuck inside.
Boondocking---do you want a generator?
Settle on the type of unit your looking for, rather than "just a class C" and keep looking in the RV Trader, Camping World Used RV lists, Craig List, ect.
Wife and I looked for 4 month's on RV Trader till we found what we were looking for, via a private seller. Drove 250 miles to get it but it was worth it.
