I wouldn't think it would be too much of an issue if you're already working remotely, at least given that you're still able to get the work done and be contacted when needed - I'd definitely make reliable internet a priority, which you've obviously considered. Good to think about it from your employers perspective though. I might be inclined to describe it as a shorter term vacation at first, rather than admitting to being on the road full time. Then you can at least point to some evidence that you're still able to do the job just fine from that experience and explain that it's become a full time thing. Hope it all works out! sounds like a great way to live.
