This is my 4439 Work Truck; my second alternate for 4439! It features two seats for minifigs, and a large back to haul whatever you need to. It has a very interesting design in that the front is 7 studs wide and the back is 8. It had to be this way due to a lack of better wheel pieces, but I like the challenge and the way it came out. This is posted on rebrickable too, so if you'd like to download free building instructions for this moc or any of my others, please go to rebrickable.com and search "Turbo8702." Enjoy!
