Recommendations for Receiving Mail while Full Timing?

I used USPS STORE. They provide a real address.
Emphasis on the word 'store'. It is NOT the United postal service.

I locate a 'USPS Store' where I am at and I sign up.

Then I go to the official United Postal Service on line and click on forward my mail to that address. https://www.usa.gov/post-office#item-213659

Post office forwarding is good for 4 months. If I stay longer than 4 months or move location you just go back and renew your forwarding to new USPS STORE where you are at.

Lol I did this for over 6 years! :C
