Welcome to NuRVers, Ralph! This part of the process can be a bit overwhelming - so many pieces of the puzzle to find and put together. Luckily, there is a lot of information readily available on all the different parts.
Two really good resources are RV.net and the Escapees forum - http://www.rvnetwork.com - for basic RV info and fulltiming information. http://www.fulltimefamilies.com/ and http://familiesontheroad.com are both great for the family aspect of nomadic life.
Keep us posted on your research, and be sure to ask any questions that might come up. There is a wide range of experience here at NuRVers, and we all love helping out when we can!
Again - welcome to NuRVers!
