Boondocking is definitely something I would want to do. There just don't seem to be many places available near the city of Nashville. I plan on working in/or around Nashville. I am also a musician so I would like to be able to close to the city for that reason. Again, its probably wishful thinking to want to be close to an Urban area AND have good, free, outdoorsy boon docking sites.
I have called about monthly rates from many of the RV parks near the city. They are mostly in the $500 and up range. That's fine, and it's what I will do most of the time, but if I can boon dock for free 4 months out of the year, thats $2000 saved. That pays for my solar power system. I realize boon docking isn't entirely FREE, but even if I managed to save $1000 in a year....
A class B or B+ would definitely be more stealthy, but as a musician, I have a lot of gear and just need more space.
I might just have to suck it up and pay the monthly rates at the RV parks. I'll save to boon docking for when hit the road with a band. I won't need any long term places then, and Walmarts and bar parking lots will suffice.
I appreciate the suggestions, and I have bookmarked the links posted above! :D
