Odd, but the three Trilliums I looked at last year, all were on Craigslist, none made it to
fiberglass RV 4 sale site. Not sure why?
But yes, the scammer ads like this one are still pretty easy to spot. A google search of the phone number on this ad links it to several scam ads.
For someone seriously looking, Craigslist search tempest is the way to go in the USA. Still have to know the difference between a scam and a legit ad as there are plenty of scam ads on C/L.
Offer Up and Let Go have a feedback system that limits scammers. Unfortunately, they are not that popular yet.
