Good luck on the endeavor, but I am in with the naysayers. Most towns, you will be paying $30-35 a night for a RV park... or trying to camp at WM, only to find a local police officer knocking on your door at 2:00 in the morning with a $100-200 citation for some anti-camping ordinance violation or another. Using a RV that is parallel parked as a house did work in times past, but 2008 killed that for everyone, and now cities and counties actively search out motorhomes as "prey" because it adds to the town coffers without any taxes on the local voters.
Even the van dwellers are a dying breed because the medium to larger cities are using helicopters with FLIR to locate occupied vehicles at night.
However, if one wants to try full-timing, I'd chime in on getting something other than an "A". A pickup + TT is a doable option, and has a lot lower cost per mile than a class "A" rig. Plus, you can buy a lot newer tow vehicle and travel trailer than a class "A" for that price... and newer means parts are cheaper and easier to find, and more places to have things fixed. Finally, "A" parts are relatively hard to find, especially a 1980s rig. A pickup truck from the Smashing Pumpkins era, or even the Britney Spears era will have parts that are fairly easy to get ahold of.
If you have to have a motorhome, go with a "C". Easier to repair.
Every so often, rv.net gets a post by someone who has dreams of RV-ing it full time. This was possible 10, maybe 20 years ago, but now, it is something that isn't really possible. In Texas, for every workamping position available, there are usually 10-50 applicants. In this economic climate where even Wal-Mart has lines around the building for part-time positions, it becomes very difficult to just "hit the road" and expect to succeed.
I hate being a downer, but I'd focus on trying to find a niche and try to separate oneself from the herd of college graduates in a perpetual search for work. After getting a career steady, then go look at RV-ing.
