Gas vs diesel light medium duty wrecker?

[JasonElyriaAuto]

Looking to replace a truck that was recently stolen, our only light wrecker (A Dodge 5500 Cummins). Considering used Ford and International trucks (Obviously International is not available with gas engines). Who has used a gas wrecker in a 450 - 550 - 650 configuration? Looking at overall operating cost. Our trucks really do not run a lot, no where near all day long. Thanks.

I have one F550 Gasser that I drive myself and it works pretty well. The 7.3 has plenty of power & matched with the 10 spd does a good job. 

 

 

It's lighter in the front by nearly 1000lbs over the diesel which can be an issue. We installed a counter weight behind the bumper that narrowed the difference some. I would say the cost of operation is similar due to a little less fuel economy but cheaper at the pump. It's certainly cheaper to service & what not. This unit only has a little over 10,000 mi on it so we haven't had any unscheduled repairs needed in the last 2 years I have ran it.
