New Year, new career

I think it's time for a Change. I am a Scrub Nurse and listen to others talking of early retirement. No chance for me, as I qualified 4 years ago, so I will be there for many years yet. The idea is to do agency nursing throughout the country, with retired husband and dog in tow and stay in our caravan. This will allow us to travel further afield and spend more time together. We will go home for holidays instead. Has anyone travelled and worked away like this before? Did it work for you? Any advice will be much appreciated.
