I have an '05 Ford F350 with the 6.0 powerstroke diesel, and I love it almost as much as my '03 745i and '04 X5 4.4. Yes, the diesel is a little noisy, espcially since Ford went on a cost cutting spree and took out the hood insulation. I recently added the stock hood liner, and added Dynamat to the inside of the doors and the ride is much quieter, at least on the inside. As far as trucks are concerned, I'm a fan of the diesel.
