It costs more to maintain a diesel...oil change, brakes and most other parts. Then, it costs more to maintain a 3/4 ton or 1ton also. My boss had to pay quite a bit more for a wheel bearing ($750 for his ford 250 vs. $270 and some change for my buddy's chevy 1/2 ton). That's been about five years so I'm not exact. I personally would have bought a diesel instead of my current truck, but I'm poor.
