Avoid Facebook marketplace. Craigslist is $5 to list and works great for me.
Consider using Bringatrailer or Carsandbids, they are popular and really well run. Small fee to list, under $200, and you will get buyers with $$. Ebay is pretty garbage with fake bidders and buyers who can't pay. It can work but it will cost you more out of pocket.
I know of a few people declined recently at BAT. Not sure why, but the last 4wd van I saw for sale on there went for way cheaper than I’d want to sell my van for.

I’d be seriously bummed if I owned that van and it only yielded 21k, but sofa king stoked if I was the buyer! I guess unless the owner didn’t need to make any money off of it. Who knows, but I couldn’t chance it personally.

I sold my van recently and I received a surprising amount of quality interest from Craigslist so I wouldn't immediately discount that. You may have to filter out a few people and not respond to some messages but make it clear you are looking for serious buyers and they will let you know by their response if they are. I also posted on this forum and RVtrader.com. I ended up selling to someone from RVTrader and received a good amount of interest from there as well. My recommendation is Google "Used Sportsmobile" and see what comes up... because that is what your buyers are doing. This forum and RVTrader were ranked pretty high for that.
