Hinder. It’s a pretty accepted and a known fact that the second you add windshields, the dust problems immediately become worse. The more you encapsulate the cab with windshields, coverings and partial cab enclosures, the dust magnifies. Most dealers are aware of this but don’t want to jeopardize their ability to make money on aftermarket products. They will continue to push windshields and even recommend them for all dust related issues. It’s very counterintuitive and costs customers thousands of unnecessary expenses. We realize that in certain conditions that a front full windshield is wonderful and useful. But, you can still achieve similar results with a front half shield or something that allows as much ventilation coming through the front. The more ventilation, the better the dust control and maximization of the spoiler. We sell a lot of product to customers that have full front windshields and they are all still happy. We offer this information to understand and gain the maximum benefit possible if desired.
