6′ x 12′ x 3500# – Utility Trailer Plans

Description

The 6×12 utility trailer is the most popular of our 6′ wide trailers.  It is great for landscaping projects, ATVs, moving, business, motorcycles, . . . you name it.  A lot of volume, yet very maneuverable, and it tows great.  Build this trailer in a great size, and build it to last.

Like all our trailer plans, these include many great options that you can choose to make the trailer perfect for you.  The base trailer is a flatbed, but you can choose sides, ramps, a tailgate, or other functional options.  All in the plans.

Choose from various components that will make the trailer best for you.  There are also great extras like various tie-down options you can choose – or add your own creativity with variations.

We provide the fully engineered trailer frame and design, then give ideas and many choices.  All, so you can build the trailer the way you want it.

These plans for a 6×12 single axle utility trailer are 3500 lbs capacity.  It is strong, by design with full engineering.  The purchase includes the complete trailer blueprints as well as instructions with lists of materials and components – plus tips to help you build it super well.  Buy the plans now, download them, then start your project in just a few minutes.

The main plans are a leaf spring design, HOWEVER, if you want a torsion axle instead, we also have Torsion Axle Conversion Plans for this 6×12 utility trailer.  See the Alternate Sizes & Conversions accordion below.  We have you covered in making the trailer perfect for you.

We have alternate sizes, like –  6′ x 10′ Utility Trailer Plans (a little smaller) – or –  6’10” x 12′ Plans (a little wider) – if this is better for you.
