Don't wait go do it now. You will find you can only see a tiny piece of all of the states in a couple of years. There is just too much to see but I think it is still worth it. You can always go back to the states where you want to see more of at a later date.
If you or your husband aren't handy at fixing stuff might try to learn some of that. Things will break and you won't have the time to schedule an appointment somewhere to get it fixed. Luckily someone on this forum has had the same issue so you can ask and more often than not get the answer on how to troubleshoot the issue and/or fix it.
Decide on what your goals are, Parks or Cities or both, etc. That can help decide the type of RV. After going to a couple of big cities and actually some of the more crowded National Parks, we have often talked about how a Class C pulling a smaller vehicle would have been a better choice for us. A big truck is just a pain to find parking for, (except maybe in Texas
) If we had the money, we would get a DX3 and pull a jeep, (dreaming right now).
It sounds like your husband will be working, which is my situation. I wish I were retired is all I can say about that. It severely limits what you have time to do/see.
One last thing that really worked out well for us is the school where the kids go have an online school program, mainly for kids that can't go to class. It is the same curriculum that they would have got if they were going to that school. It also is free,
check to see if your school offers that, (if your kids are going back to the same school when you are done with the 2 years).
There is just too much, there are many sites that you can read and learn. Google "full timing in a RV". Full Time Families is one, Escapees is another. Or just do like us and learn as you go, but for sure go!
