Lots of great advice. Like others have said an RV show is a great place to look at 5th wheels. One important thing I have learned is don't believe a salesman. I've been told some many untruths from various dealers. I'm not saying every dealer is like this but many are. In addition to finding a floor plan you can live with pay attention to the suspension, tires, frame, overall construction. Does it have a convenience / docking station. Are the dump valves easily accessible. Go to the various manufacturer's forums & see what owners are saying. Keystone, Forest River, Jayco etc.
If you order a 5th wheel leave yourself an escape. Make it subject to final approval.
Good luck.
