The same RV mail forwarding services that fulltime RV'ers use often also offer service for long timers. Since you're based in Florida, a company like
St. Brenden's Isle might be a good choice. After you set up your account, you would just use a temporary forward with the USPS to send your mail to SBI instead of permanently changing your address with all your contacts. An added benefit is that the USPS does not forward junk mail. Periodically, you then just ask SBI to forward your mail to your current or next location. If the park does not accept guest mail, have it sent to General Delivery at a nearby post office.
