How to deal with mail while you're on the road
Many RVers have their mail forwarded to friends, family members or neighbors who will, in turn, forward it along to them. An even easier option is using a mail forwarding service. Yes, there is a fee for this, but it is usually minimal. According to rv-info.com, many RVers also use the state their mail forwarding company is located in as their legal state of residence. This allows them to pick the state with no income tax or a low annual RV registration fee to save money.
Although it may sound like a good idea to have mail forwarded to a campground you'll be staying at for an extended period of time, many won't accept it. Always check in advance before you try this! A better option may be to have your mail forwarded via General Delivery to the post office in the town you're visiting.
There is also another option, through a service called My RV Mail, that will collect your mail, open it and scan it into a PDF document so you can view it online.
