It is funny how some are saying that others are just trashing Ram. How am I trashing Ram when I am saying another Ram product is better for saving money? I also own a Ram too!
Also, that Ecodiesel didn't quite tow as well as most here are trying to say. When those guys tested the same Ecodiesel in the Cherokee towing up they Ike Gauntlet, they mentioned how the temp gauge started to climb. In the video the OP posted, you see that temp gauge start to get up to H before it goes back down again. Even DieselPowerMag who set up an actual read out for the temps said "With the accelerator stapled to the floor, the truck’s speed dropped off to 53 mph, and engine temperature climbed to an almost alarming 244 degrees. Thankfully, as we crested the summit, the engine temperature returned to normal"
So how is running hot or close to hot towing well?
