My lunchbox is one of my favorite trucks, I've had at least one for about 12 years now. I've gone through many different hop-up configurations: dual wheels, dual shocks, modified a-arms, oil damped shocks low turn motors, ect. My favorite though is still a bone-stock truck with an MSC for wheelie-poppin fun. On my runner "truck" I have been using an HPI concept one body which is attached to the chassis with velcro at the front and rear of the chassis, which provides cushoning and with the round shape, it often ends up back on its wheels.
