Ken56 brings up a good point about mail: being able to recieve bills/pay them via internet is wonderful. Otherwise, have your post office hold your mail (or a trusted person handling it). When we go south for the winter, we pay the insane price for premium mail forwarding, so all our junk mail catches up to us (rolling my eyes) but at least we wouldn't miss out on something critical.
Back to the internet: RV parks' wifi is not always good (or overloaded). Either get up before sunrise to log on; or bring your own hotspot.
