The 6′ 10″ width (frame between the wheels) is basically the widest you can tow without permits. This trailer maximizes the space available at full width. Then, the 12′ length is great for getting the jobs done. It’s a great trailer for business, landscaping projects, carrying toys (like ATV’s, UTV’s, Side-by-Side’s, etc..), . . . you name it. Lots of deck surface area to work with.
Build the trailer you want in the size that makes most sense to you. Most of all, build it to last! You can be confident with plans from Mechanical Elements. Like all our plans, these include the full array of engineering. We won’t sell anything less.
Also, like all our trailers plans, these include a lot of options so you can make the trailer perfect. Choose the ones you like – sides (of various styles), ramps, tailgate, or other options. There are component options too. And, a lot of functional extras like deck materials to choose, and various tie-down options. 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′ 10″ width x 12′ length, single axle, utility trailer are 3500 lbs capacity. The base design is for leaf springs, yet, if you prefer, we also have a Torsion Axle Conversion for it. See below.
We have alternate sizes — like a 6×12 — 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.

* 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.
