A few pieces of feedback. In the suspension section, it would be worth explaining a few things about truck suspension, also. Like solid axle, front and rear suspension, both with Coil and Leaf springs. Also, dampers are incredibly important in large trucks/SUVs because if they fail, body roll has much higher likelihood of causing you to lose control. Finally, a "bounce test" really won't work with many SUVs or truck where there is simply no way to compress the suspension to any meaningful degree with your hands.<p>personally, with trucks, I like the "speed bump test" where you drive into a speed bump and if the truck/SUV continues to oscillate upon returning to the correct height, your dampers probably need work. Additionally, since most trucks/SUVs use similar oil volume dampers to cars, the life of their dampers is frequently lower than in cars. The ones in my TRD Tundra lasted about 40K miles.
