I feel your pain. We spent the entire winter on the road last year and stayed home this winter to sell the house and by a condo. The good news is I haven't touched a shovel yet, which is nearly as good as not seeing any snow at all.
I'm with John&Joey; six months was ok for the first big adventure, but I think future trips will be limited to 3 months at a time.
If you'll be moving around Florida next winter, don't miss the panhandle. We enjoyed this area of Florida. There's a reason they call it the forgotten coast.
