First bit of advice is to fine a good forum that has FULL TIMERS on it most of the time. Escapees (www.rvnetwork.com) has more fulltimers than any where else. There is also a Full Timers section on RV.NET and one on iRV2.com
Second bit of advice is to read the blogs of people who post in fulltime forums and who have been fulltiming for a while - we're still relatively new to it having only been out a little over 7 years now.
Third, spend at least a weekend couped up in your RV in the rain and see how things go. If you and your spouse aren't best friends, it probably won't last. RVing fulltime is a challenge and it requires a LOT of patience, perseverance, the ability to make Lemonaide out of Lemons, a sense of the wanderlust, and the ability to enjoy doing NOTHING at times - because you do need down days when you do nothing.
2-2-2: Don't travel over 200 miles a day, stop by 2:00 pm and spend at least 2 days at each stop. You won't be on vacation, so take your time. There will be times when you need to go quicker than that - but try and enjoy the trip and slow down and find the whimsy in life.
Again, get on some fulltimer forums.
