During heavy crosswinds, the truck has been influenced by the wind currents. I'm gonna run a tankful or two without the side skirts on and see how the truck will respond as well as the MPGs. Looks kinda strange without them on there...but it's all fer science!
Maybe I'll come up with another side skirt design that will allow crosswinds that exceed a certain amount of pressure on the side skirts to pass through instead...or even cut down the ones I have.
Sans side skirts...but the rear wheel skirts stay.
