Wow, you're really getting a head start. I think it took me about 2 months to plan our cross country trip. But then again, I don't like to make reservations--just hit the road and see where we end up. We had two kids with us, 12 & 14. Best vacation EVAH. I can't recommend it enough!
I know a lot of RVers, but I don't know anyone who has ever had their rig stolen. Personally, we prefer a trailer over a motorized unit. Fewer systems to go wrong. I like being able to drop the trailer and use the F250 to get around, rather than having to fool with a toad. For us, smaller is better anyway. We've had pop-ups and trailers, one of them a 30-footer. Not for us. We have a 25-ft trailer now and it's probably going to be our last rig.
