If you are a "part timer" and you are going to be gone awhile, you can get by up to about three weeks. That's what I did.
THen, when I started taking LONG trips but still had a "home base," I used the Postal Service's premium forwarding. Now, this option only works if you are going to ONE location for an extended stay. You can't say, "ok, this week I'm here, next week I'm there..... etc."
Now, I am using UPS Store. UPS Stores or Mail Boxes etc will forward your mail and you can be a different place each week. The caveat is that you have to change your address and have all your mail go to the UPS store or Mail Boxes Etc. (I think UPS store bought out all the Mail Box Etc. stores...)
JJ only, my cat went to Rainbow Bridge July 2015
I love my Sunseeker, when I'm on a trip I don't wanna go home!!!"
Total days camping each year: AS MUCH AS POSSIBLE!
