Please don't take this the wrong way, but if you have already decided that you are going to 'fulltime for a year' you will find yourself in vacation mode the whole year and at the end you will be exhausted, you will both say it wasn't for you, and you will no longer go on the road. You are setting yourself up for failure. It takes 2-3 years just to get the bugs worked out and settle into a comfortable style of traveling. If your wife is already putting up road blocks she is letting you know that she doesn't want to do this and at the end of the year you will be back in that house. Plus, because you only have a year, you will have rushed around and won't have seen as much as you want. Better off to try just snow birding for a year or two and then see if you want to full time.
