Where can I view and purchase used trucks online?

When someone (an individual buyer, dealer, company, etc.) wants to buy a used car, he looks at some main sites: AutoTrader, eBay Motors, Craigslist, Cars.com

I want to know where truck buyers go to buy used trucks. Looks like eBay Motors does not offer such a large selection. Where are most used trucks sold online? I have found TruckShopper.com, Super Truck Center.


Are these commercial trucks or personal trucks? Give us an idea what type of truck, too. By type, I mean small commercial box van, like an Isuzu/GMC or dump truck.

autotrader.com has a decent number of vehicles of all sorts…
