6 x 12 Utility Trailer Plans Details:
All our trailers are designed for Strength and simplicity with standard beams, gusseting and triangulation for rigidity. They are fully engineered to be strong, by design, starting at the frame, and they do not rely on sides to meet capacity. Yes, sides options are included, but they are not required. The frame is the solid foundation built to perform and to last.
Towing Stability, is achieved with engineering design fundamentals to tow easily. Plans include adjustable options for various load types. Equally important is Maneuverability, so the tongue gives proper vehicle spacing.
Design Versatility is in the plans — with axle and brake choices, load and deck height variations, sides (or not), a top (or not), and deck material choices. Options include ramps or tailgates like a fold down tailgate/ramp combination. — All are included.
