Description

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.
