This is based off the old Lego® kit 5580 “Highway Rig” from 1986 Model Team series. The undercarriage is identical to the 5580 kit, but I changed the colors and used a few more modern Lego® pieces on the body. I also removed the spare wheel from the back of the cab and added a caution light to the top of the cab, which is used to steer the front wheels. UPDATE 1: march 1, 2008 I decied to update the truck just a little, mainly the engine compartement, but I also added a small ladder to the back of the cab. http://www.fettsplace.net send comments to: fettsplace@yahoo.com
