If you have a sticks and bricks house and want to keep that address for your mail, you are limited. The Post Office will not gather and send your mail periodically to different addresses. Your best bet would be to hire an neighbor or friend to gather your mail and forward it at your direction.
Alternatively, you could rent a PMB (private mail box) at a UPS store and change your mailing address to that new PMB. Then call the store and direct them to send your mail. This does reflect on your credit history as a new address.
If you live fulltime in your RV, then mail forwarding services dedicated to this lifestyle work very well.
