It's hard to make any recommendations with such a broad, general post. But:
Where do you want to go? Pretty much anywhere that has roads can be traveled in an RV, with limitations of quality of roads and size/ability of the RV and its driver.
Will you be renting or buying? You might start by going to a couple of RV shows, where vendors have booths and displays of both rigs and RV parks/campgrounds.
And you can do a ton of research on-line, driving yourself crazy with making choices. We have a 5th wheel, pulled by a pickup truck. For self-contained rigs, there is everything from amped up minivans to converted Greyhound buses. The rental market is primarily small to medium-sized rigs.
RV parks and campgrounds also include a wide range, from US Forest Service campgrounds, to national parks, to private parks with a wide range of amenities.
www.rvparkreviews.com is a good website for research, or the Good Sam Club.
Do you have specific questions to narrow down your inquiry?
