One thing you need to really consider before giving up your current life style, is the cost of full timing in any RV. Although it sounds like a cheap way to survive, it can be very costly. You have the initial expense of purchasing the camper (whatever type you get), there is still insurance, dealing with the logistics of maintaining a permanent residence, the cost to travel, and the cost to park the camper somewhere if you want water, electric, and sewer.
Even if you get a camper that has solar power available, you still have to deal with a water supply and sewage.
Not to discourage you, but you really do need to do your homework first and have a plan. A short term plan and a long term plan. Northern states freeze in the winter, Southern states get blazing hot in the Summer. Campsite cost. They can range from $20 a night to $100 a night. You can't boom dock forever. Eventually, you need civilization. Then you also need a contingency if the RV needs repairs. If you have no home, that may mean motels, or staying with family.
The upfront cost of a sound RV will bite you financially, and they you may still have shake-out / shake-down issues to fix on top of that.
Basically, RVing is not a cheap way to survive. It's actually a costly experience. Once you start down this path, its a loosing experience if you decide to get out of it, meaning, you will never get back from selling an RV what you purchase it for, or cost of what you put into it to maintain it.
Still many do full time in an RV and are quite successful. You can do it too, you just have many things to plan out and be prepared for so you won't have upsetting events that will be devastating to you in the future.
