Sorry for your loss too. Sounds good that you are trying to think things through without rushing.
I bought and sold several RVs, cars, boat, on Craigslist. Have no experience with MH magazine. You will likely get more money from a private sale than trading it in (or consignment) with a dealer. You just have to determine if you want to spend the time and energy to deal with showing the RV to potential buyers.
What I did when selling is first talk extensively on the phone to the interested party to determine if they are really serious about my particular model. I didn't want to waste time with lookey loos. Once I determined they were serious, I arranged a time to drive the RV over to a large public parking lot, like Walmart or Home Depot, to meet them. This is if you don't want people coming to your house (if the RV is parked there.)
Make sure the inside is neat and clean, and people will love it, if they are already interested in that manufacturer/model/layout/size.
I dealt only in cash. Sometimes I and the buyer met at a bank and then went to the DMV together (not necessarily needed, but in one case it was convenient). Or I just took the cash and handed over the title. Or one time I took half the cash. Later that day, I stopped at a bank to make sure they were good bills (without buyer knowing), then drove the MH over to the DMV to meet the buyer, who by that time had the rest of the cash. Just depended on my gut instinct about the buyer. I listen alot and ask alot of questions.
Lots of ways to sell. As mentioned, there are also other online avenues like RV Trader, etc. Just be careful of scammers if you do private sale. Use common sense. Best of luck to you!
