RVs sell locally, most of the time (unless they are high-dollar and rarer than normal). Craigslist is the best, and sometimes Facebook can sell for you.
For these kinds of purchases, people like to look at units that are close to home and ones they can visit. Spending money on a country-wide venue generally doesn't pay for itself.
If you aren't familiar with scams, ask a question about how to avoid them, or hit the SEARCH function for internet scams.
