Not sure where to go?

OK... this isn't specifically for RV travels, but if you are just itching to go somewhere but don't have a destination in mind, Tripbase may be just what you need. You can tell Tripbase when you're leaving, where you're leaving from, what your budget is, and what kinds of things you're interested in (nightlife, dining, attractions, nature...) and it will find locations for you.

Be sure to select only North America from the destinations search list. I don't know about your RV, but mine is strictly land-based.
