Just wanted to thank everyone for their input.
We will go fulltime August of 2016 and here's what we've decided to do. Hopefully it works for us!!
Per all the suggestions -
Express Script is the way to go. We currently use them now, so not a big deal to continue.
We'll most likely stay someplace for the winter, so we'll find a primary there and work out the scripts with him.
ALL medical records will go onto a thumb drive and allow us to carry while travelling. This will help if we need to see a Doc on the road.
Thanks again,
-paul
