This file prints six log truck frame end kits These are designed to go behind normal truck frames to more closely resemble the frame types seen in the logging industry. There are 2 of each of the frames; trianlge drop frame, square end frame, square end frame with extendable stinger. The details included with with each are positionable mudflaps, light bar, and wheel rests for a mule train or short logger if that's the type you're wanting to build.
