I'll be posting an analysis of my expense projections (and the real numbers for the few days I've been living in the RV) sometime today. I haven't run the numbers for a hotel, as it wasn't a feasible option for me. If you don't mind staying in less interesting places most of the time, you can probably do it for roughly the same. But, high rent cities will probably kill your budget (though, there are usually cheap hotels in every city, if you don't mind living in a ghetto and in a crappy hotel). Since I can theoretically just park somewhere (Wal-Mart, neighborhood street, etc.) in even the toniest of locales, I can probably visit the highest rent places in the country without paying a fortune to do it. We'll see how realistic that turns out to be over the next year, as I visit Los Angeles, San Diego, Austin, Atlanta, New York, Toronto, San Francisco (I've lived down in the bay for 3 years, but never really properly experienced San Francisco), etc.
Weekly stay hotels would also probably bring your expenses down a bit.
