James- I tried to call you and left you a message. These chaser vans are everywhere. I used to work for a company that built these (Frontline Communications) in Clearwater Fla. They would come to us with no miles and we would put all of the rf equipment as well as masts in them. Is what happens is these big news companies like ( ABC,NBC,CBS,CNN) keeps these for a year and then pulls out what equipment they need and sells them off. You mostly seem them at the end of the year or the begining of the new years when they get their funds for buying new vans and equipment. So basiclly they just drive them for a year with easy miles and then pull out what they need and then just sell tons of these off. These van are usually in great condition. Hope this helped ya a bit.....
