International says the ProStar has also been optimized for service. In fact, the truck builder claims this adds up to 59 fewer visits to the shop over a 10-year life, contributing to its lowest-cost-of-ownership objective as well as to vehicle uptime.
From a technician's point of view, the swing-down front bumper and the removable side skirts are a plus. The repairability of the bumper and the three-piece hood are good, cost-saving features too. I'm not so certain about the big, one-piece windshield. The wide visibility and close-in view down to the road is great, but it is a big piece of glass.
Air and electrical connections at the back of the cab can be reached from the ground, and check and fill points under the hood are certainly easy to get to with the swing-down bumper.
Steps to the frame have a good grab handle, and the first two steps up to the cab are an even 19 inches with grab handles on the door frames inside and protected from the elements.
I came back to the ProStar with high expectations and was not in the least disappointed. It was just as good – even better – than the prototype I drove a year ago. It is formidable competition to the other premiums in the marketplace and will likely bring a lot of conquest deals.
Undoubtedly, ProStar is a great truck and, especially in this pretty red Limited edition, very attractive. And here beauty is far more than skin deep, because the truck is all-new, well thought out and well executed. It is a driver's truck for its quietness and handling, and it's an owner's truck for its low maintenance and repairability.
