I bought my diesel for one reason only, towing power. I don't care about the payback. As far I'm concerned it already paid me back in spades because I can now make a 1000 mile trip to Mesa, AZ and use the cruise control 75% of the time vs. none of the time with my 6.0L Vortec. It tows up the hills and brakes me down the hills 10 times better than the 6.0L Vortec ever did.
