Both set ups have their advantages and their disadvantages. It's all in what you want. I've had no issues at all with the V-belts on my truck. In fact, I also prefer them just because if you happen to lose an accessory (such as the A/C compressor locks up) you can remove that one belt and still drive it home with the water pump turning. On the other hand, there's the cool factor of opening the hood of a Bull Nose truck and seeing a serpentine set up. Strictly for looks, I think that the serpentine belt is the only way to go. Everything just looks cleaner under the hood.
