That's what we did this year. We were on the road for 13 months, then knew we'd return to Dallas in October, so made appointments a few months in advance for the weeks we'd be there, had physicals, etc.
Dental is the biggest pain, especially if you have insurance,. First deciding where you'll be in advance, finding a dentist taking new patients, etc is a problem. We happen to be wintering in Florida again this year, so we'll be able to use the same dentist there for cleaning right before we leave, so we're already "patients".
Make sure to take into account network availability for your health insurance, especially if you'll be in the Obomacare marketplace. It's tightening in '16 and there are fewer options, at least in Texas. Well be going outside and getting our own insurance for '16 (we're under 65).
