Been a few years since I enrolled in VA for service connected dissabilities. I never used VA tho, so am not up to date on their latest info. Would suggest you talk to your VA rep at the clinic you use, they used to only allow a limited number of change of address per year and if you plan to return to your normal clinic in the winter you may be better off just to keep an address in Fl. If you use an address from SD (as example) and are enrolled in the VA clinic in that area, may impact getting care in other areas as you travel. I get my medical care thru a facitity where I have on-line access to my Drs and records. Has never been a problem to use an urgent care facitily when traveling, because the drs can see my records/medications and are always willing to communicate with my regular dr.
