I use a private mail service here in town, as well as my home address for receiving mail. When we are going to be gone for several months, I put in a temporary mail forwarding with the USPS to send all my mail to my PMB address. They are a very service oriented business and will sort my first class from my junk mail. I pay most of my bills over the Internet, using my phone hot spot to connect.
Every couple of weeks, I will call my mail service and see what/ how much is there. They are also a UPS and Fed Ex agent so easy for them to repackage my mail and send it to me when we are going to be stopped for a few days. I keep a positive balance of cash in my PMB account for the costs for them to forward my mail, etc to me. Been using this business for about ten years and it works well for us.
The downside is that last time I did a temporary forwarding with the post office, they notified many of my senders of my "new" address, so mail I normally have come to my home address started being sent to my PMB address, . I keep the PMB address year around and swing by to check my box there about weekly, as that is where my magazines go, etc. other con is recently we decided to do a refinance of our home mortgage, and the loan company wanted to know why we had two mailing addresses on our credit reports. Just took a letter to explain it to them and they were fine with the information. Not sure why it was a concern to them but it was.
