I set this project to the side a couple times, and most recently to complete my Mack Vision due to a strong urge to design a tractor for my UPS trailers. I put the finishing touches on this Kenworth W900L tonight, and it is now ready to print. My intention for this configuration is to have another bull hauler to go with my Pete 379 on my livestock trailers. My herd bumper should fit this rig as well. This should be a beauty once I have a set of straight pipes on it. This design will have separately printed air filters like the Pete, and a separate frame and wheels. The grill is part of the cab, and the bumper part of the frame this time.
