I hope I am not to late in jumping into this conversation (I hope you have not made a decision yet.) I would strongly advise against a UPS store. We used one for a year and the UPS store overcharged us a lot in shipping fees. It was 4 years ago and the average cost of forwarding our mail was $30 each time. I won't waste your time with the many horror stories just take my word for it the UPS store is not the way to go. FYI the store we used was owned by a personal friend who we haven't spoken to in four years.
We switched to Escapees and do not have any complaints. They have sent our mail to any location we have asked them for in three to four days including General Delivery to the Post Office for $10 or less.
As to providing a "legal" legal address Escapees is set up to give you a legal address in Texas, Florida and South Dakota. Go to this link for more info on Florida. https://www.escapees.com/index.php?option=com_content&view=article&id=220
You can write to me directly if you have more questions on Mail, domicile, or best ideas for communication while full timing. We would be happy to answer any questions amecnet59@gmail.com
