Guy's,
There is no 'right' answer here. Some of us tow every so often and need a truck that can handle what we're pulling around. The rest of the time it's a driver and a general hauler. Most of us 1/2 ton guys fall into this category. We just want a multi-purpose truck that can do everything pretty well, not one thing with perfection.
I could use a 1 ton dually diesel for some of the things I do, but I can't park it at work. Which means I have to have another vehicle that requires maintenance, insurance, plates and garage space. Not practical or financially feasable in any possible way.
If you tow 15,000# every day, a half ton isn't your thing. If you tow 8,000# every third weekend, a 1/2 ton is fine if it is set up properly, which really was the issue of this thread.
