It's interesting, and disapointing, that you have not yet had any replies. Although we have a few years to go before we can sell up (the only way to fund it) and go, we have a serious plan in mind, and intend to roam in the U.K. only. There are many possible hazards, but I think a lot are perceived as problems, but can be overcome by being positive and flexible and being prepared to adapt. The more major problems not overcome yet are, apart from the funding issue, an address for legal/post/insurance/tax purposes, doctors and longer term hospital treatment etc, how to manage on just battery power in winter if funds don't allow continual mains hook-up, and ... well there are more but there is not enough space here to discuss them. Seriously, it obviously is possible, there are quite a lot of 'all year' sites provided you are prepared to move on fairly frequently. The west country is the obvious place to over-winter, if you want comparative warmth. I will be interested to read any other replies you have.
