Here's a Power Functions Dump Truck. My RC vehicles are getting better and stronger. With the LEGO Servo Motor, I was able have a better steering system and less parts. Uses just one XL motor with 1:1 gear drive m-motor for linear actuated dump bed. Conveyor belt is driven by one m-motor. The loading function didn't work and jammed up the system 99.9% of the time :P So I loaded bricks by hand onto the belt. See more pictures on my MOCpages. http://www.mocpages.com/moc.php/394925
