I'm not sure why a few guys on here are determined to attack the data and outright try and discredit it, but I know many other guys out there who are capable of identifying types of trucks, brands, years models, and the engine under the hood. Heck, my wife can tell the difference between many of them.
All the folks on here hanging their hat on the argument that one can not tell the difference of trucks approaching from the opposite lane, at closing speeds of 120 or 140 mph, etc. that's only a small part of the data collection. You conveniently overlook the trucks in the same lanes, the one's who pass, or the one's passed. And the one's fueling up at the pumps, or the one's at the campgrounds, etc.
BTW.. My personal tow vehicle is a 2015 RAM CTD 2500 4x4. I tow a 5er, 32ft, around 10.5 loaded. I have owned all of the Big-3 trucks. I've owned the Ford 7.3, 6.0 (bullet proofed), Duramax (LLY), and Ram (6.7). I've also owned and towed tag alongs with a 2500 burb and an Excursion (6.0, bullet proofed). I love all of them, I do not really have a favorite. I do most of my own repair work and maintenance, which is one of the reasons I'm currently in the Ram. I can pretty much make any repair on the Cummins without pulling the cab or engine, etc., and I love the low RPM torque. My perfect dream truck would be a GMC Denali 3500 DRW with the 6.7 Cummins in front of the Allison trans. I own a Ram only b/c of the Cummins. But as I said, I love all of them, and each of them have their own separate issues and benefits. I love trucks of all types and consider all of them a work of art in their own way.
