Where do you sell yours?

I build campervans/trucks as a side gig, mostly just dinking around for an hour or so at a time. I've sold one on vanlifetrader in '20 and it went well. I posted my new build on there a month or so ago and it was nothing but "vehicle inspection" scammers or payment scams. I got them to just cancel and refund my post. Facebook marketplace is a nightmare, and craigslist is dead. The van groups are so so but you just seem to be selling to people that already own them or are selling them. Vancamper has been somewhat fruitful but nothing serious. And experience with other places?

BTW: I'm in the US and selling a stealth build box van so it's a bit unusual for a campervan
