I took one for a test drive, the Viper engine is nice but the truck is so pig heavy that it wasn't all that exciting. And though I did enjoy banging through the gears, my Dakota R/T is a more fun driving experience to me. Then again my truck is far from stock, but even stock it just felt more like a sport truck. The SRT-10 Ram just feels big and lumbering. I'm sure it's much better top speed vehicle, but down low the torque just wasn't there. Needless to say I was a little disappointed. It was a neat idea, but it was just put in the wrong platform.
