6 x 12 x 3500 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.
Finally, there are options for Flexibility like a hidden ramp, motorcycle stands, an aerodynamic-ish front, toolbox mounting, infinitely variable tie-down placement, and more. Pictures show some of the options. We encourage you to customize the trailer for your unique needs.
Plans include complete drawings and illustrated instructions — with construction tips. They also have a parts and materials list with suggestions for purchasing components.

* Trailer load capacity depends on all the parts — axle(s), components and materials — as well as the craftsmanship in building. All these trailers are engineered to perform as stated when built as defined, and when proper care is given in construction. Capacity for this trailer requires proper choices for parts such as the hitch, axle, wheels, tires, safety chain, decking, bolts, pins, etc. Please make sure load capacities match or exceed the trailer capacity, and Do not exceed manufacturers limits.
Success with the trailer — in building and for trouble-free trailer life — depends on materials, construction techniques, welding skill, assembly methods, finishing and proper loading. Proper frame set-up and weld integrity are critical, as are bolt torques, tire pressure, tire condition and the mechanics of towing. Always use proper safety and securing equipment when loading or towing a trailer.
