Spend time reading the blogs in the various manufacturer sections. This will give you a good idea of both models and manufacturer issues. The Bounder is one of the most popular models on the road. Tiffin also is very popular. The Georgetown is also a great model. It really boils down to what you like personally. Get away from the salesmen. Do your own research and make the decision without asking a salesman. They all will tell you what you want to hear and badmouth their competition.
I purchased without speaking to a salesman, none. Did the research of over one year, then sent out bids online and then went and picked up the unit. Don't waste your time with the salesman, it will cost you more in the long-run. I've researched the two models you're interested in and like both. It will boil down to floor-plan, and what colors you like.
