You can use an RV as a mobile office. I spent several months driving and staying around the southern US, going from campground to campground. I would simply look online before pulling up from one campground, to find my next destination.
Most RV campgrounds are quiet and pretty, and no one bothers you in the privacy of your motorhome.You can have everything you need in the RV - your desktop, a printer, scanner, comfortable desk chair, cold bottled water, snacks, or a coffeepot. You can even take a nap in your own bed, with your own pillow.
KOA is reliable for having WIFI, but more and more smart campground operators realize that free WIFI = business they would not have seen otherwise. It's worth it for me to drive some miles off the freeway for a nice place to work.
Campgrounds are cheaper than hotels, for the most part, so if you've got the travel time, an RV can also appeal to your budget. Since gas prices are so high, it's nice to combine your RV trip with stopovers to scenic destinations as well.
