But I still need to plan on where I'll be in order to receive the mail once a month.
I guess I don't see the problem. Sometimes we land at an unplanned spot and once there, decide to send for our mail. We make the request and give them the nearby small-town general delivery P.O. address. We receive it Priority Mail in 2-3 days.
If you want the mail to be at that P.O. on the day of arrival, just make your mail request 3-4 days prior as you're traveling to that place. Pick up you mail and continue on.
We've never had problems doing this - even as we traveled to Alaska where we didn't make reservations. Even to Alaska, our mail arrived in 4-5 days max, sometimes shorter.
Good luck figuring it out. :)
