I own 20 it has adjustable pedals, seats, and an adjustable steering wheel.
I wear 11 extra wide shoes. I have had the truck for just under a year, and as of now no appreciable knee pain after driving the truck. I routinely drive the truck for 2-hour blocks of time. The seat cushion is a bit hard and took a while to get used to, but now no complaints about the comfort of driving or post-drive in the truck.
Perhaps there are other causes of the reported surgeries. Have there been correlation studies to show the trucks are the causeation?
I would love to read the peer-reviewed journal articles into this matter, please post links to this research.
