Hi Rich:
If you really don't know black water from gray, I would suggest buying an RV Buyer's Guide at your local supermarket. In that way, you can start to learn about RV construction, floor plans, tanks, and lingo. It will help when you talk to a dealer or seller to know what they are talking about. Also, you are not too far from Hershey PA. The country's biggest RV show takes place there in September. You can see various models, floor plans, options, and even buy if you are ready. Even if you don't buy, you will come away knowing a lot more than you did before going. Finally, before buying, try to have some idea of how you will use the RV the most. Camp at a favorite lake, travel the country, go tail-gating at Ohio State games? This will help direct you to what you need to have vs. eye-candy.
Best wishes, Bob
