For those wondering, yes they are basically a Sprint Cup chassis with truck body panels and a reduced HP engine. The COT was designed with features from the truck series, such as moving the driver inboard a little and making the greenhouse a little taller. It should be an interesting show for sure!
One thing I've noticed during truck races is that they almost never adjust the wedge or sway bar during a race. I don't know if it's not allowed or difficult to do? Their races are much shorter generally so they don't pit as often, another cost saving measure.
