OP here -
The RV is sold. We put it on Craigslist, the first people came to look at it 3 days later, they put an offer in 2 days after that, & then we did the financials & title transfer about a week later (wife was out of town so couldn't do sooner).
I was at work when they came to look at it so my wife handled showing it. She is pretty familiar with how everything works. She did accompany them on the test drive. They were an older couple about to retire so we (she) felt very comfortable going along.
We went to the DMV together. We signed the title over to them so the VIN is now officially in their name. They already have insurance. The plate stays with the vehicle for the state we live in.
They then gave us the payment. They did not finance the purchase. They use the same bank we do. They got a cashiers check. The difference with a cashiers check (vs certified check) is the funds are removed from their account & basically put into a bank escrow account when the check is issued. That means that they couldn't stop payment on the check for example.
We were surprised how quickly it sold (approximately 5 days). Truth be told, we would have preferred a little bit longer so that we could have finished more of the season. But then I thought the timeline could get longer the later you go into the season so we moved ahead now. We've had 2 pop up's & now this class C. The pop up's sold in the first weekend to the first people who came to look as well. We just thought it would take longer being a bigger purchase. However, the unit was in excellent condition mechanically, operationally, & from an appearance perspective.
Just wanted to update those that provided great advice in response to my questions.
