We began full-timing March 1, 2007. At that time we chose a forwarding mail service in Sioux Falls, SD. , mostly because they are more friendly to retirees, etc. We licensed our vehicles there, established a voting address, etc. The service has worked well; however...almost monthly we get a mesage from insurance, medicare, other services we have indicating the change of address may have removed us from their coverage area. We have explained that we are physically located at a different address and that this is simply a forwarding service. I know that we are not the first to have experienced these problems; but am at a loss as to how to handle this. Any recommendations regarding health insurance or other avenues to solve this hassle?
