Description
The 6×12 utility trailer is the most popular of our 6′ width trailers. It’s great for business, landscaping projects, ATV’s, moving, . . . you name it. Lots of volume, yet very maneuverable and it tows great. Build the trailer, in a great size, and build it to last.
Like all our trailers plans, these include many options that you can choose to make the trailer perfect for you. Choose sides, ramps, tailgate, or other options. Choose from various components that will make it best fit your needs. There are several functional extras like various tie-down options you can choose. It’s your trailer, so we provide the fully engineered base, and give ideas, then you build the trailer you need.
These plans for a 6×12 single axle utility trailer are 3500 lbs capacity. This is a leaf spring design, yet, if you prefer, we also have a Torsion Axle Conversion for it. See below.
We have alternate sizes — like 6′ x 10′ or 6’10” x 12′ — if that works better.
Open “Alternate Sizes & Conversions” below to make this a Tilt Top Trailer.
For a Torsion Axle, we have a conversion for that too.

Notes for Success
* Trailer load capacity depends on all the parts and materials, as well as the craftsmanship in building. All Mechanical Elements trailers are engineered to perform as stated when built as defined with proper care in construction – including parts, material, construction techniques, weld integrity, assembly methods, and finishing. Capacity for this trailer also requires proper choices for parts such as the hitch, axle(s), wheels, tires, safety chain, decking, bolts, pins, etc. Please make sure component load capacities match or exceed the trailer total capacity. Do not exceed manufacturers limits.
For trouble-free trailer life, think care and safety. Please select fastening methods to handle how and where the trailer will operate – including vibration, proper fastener types, bolt grades, torques, and nut types (like lock nuts). Then, be smart about loading the trailer, load distribution, tire pressure, tire condition and the mechanics of towing. We want you safe to enjoy your trailer for a long time ahead. Always use proper safety and securing equipment when loading and towing a trailer.
