Get yourself on some full-time RV groups. The expense are different for each family. You need the RV, are you paying cash or will you finance? You will need full-time insurance, Ive seen this cost anywhere from 200. per year to 2000. You will have monthly space rent, propane, laundry and utilities. Utilities aren't always included. I would also have a hefty emergency fund if you aren't handy. Things break when you least expect it. You will also need a tow vehicle unless you find a place that don't require it. That will add monthly expenses of a vehicle. Start on YouTube there are lots of vlogs out there.
