Quint Da Man,
I've been letting others respond to this thread, but all I would like to suggest to you is that for your intended purposes, and especially if you're even remotely considering some of the "Super C's" mentioned, I think you owe it to yourself to check out Class A rigs. Depending upon your preferences, you should have lots to choose from in both gas and diesel models, and should be able to stay within your budget. Well, the diesels you'd most likely have to go with something a bit older than your stated preference.
Anyway, just a suggestion. Generally speaking the Class A will give you more livable space inside for any given length, usually better exterior storage and larger holding tanks the E-450 based C's. However, if you are looking at the Super C's, that probably won't be the case.
The important thing is to investigate all of the possibilities and do your research BEFORE you buy. I'd recommend going to
RVTrader.com to get an idea as to what you can get for your money.
Good Luck making your decision,
~Rick
