One slight clarification is that AC trucks still have contactors, just not as many. Also, they are not really high maintenance, compared to the multitude of other problems that competitor's trucks have.

I would like to know where you have found this data of a 30% longer run time. All the findings I have seen do not show that big an advantage. It's possible you achieved a much longer run time with a newer model of truck, but can that all be attributed to the AC technology. Please be careful when you are comparing items. Compare apples to apples.

One final correction.... Crown does have AC truck offerings. I know for a fact that the very successful RR truck has an AC option available. I think the ESR truck may also have an AC offering, but don't hold me to that.
