Description

Description

These plans are a best seller.  A trailer made from these 5×8 Trailer Plans is better than a pickup truck for yard work, moving, or for taking the motorcycle(s).  The trailer is designed strong with the right materials in the right places.  C-Channel and Rectangular Tube for a sealed design with optimal strength and weight and corrosion resistance.

Options on Utility Trailer PlansPlans include easy to follow, illustrated instructions, a materials list, a parts list, suggested places to purchase the parts, and construction options.  The animation shows some of the options in the 5×8 Trailer Plans like a landscape style hinged tailgate, and various sides.

The trailer design is strong even as a true flatbed.  Sides add utility, but are not there for strength or stiffness.   There are also several deck options like plywood or 2x dimensional lumber.  You choose how it all comes together.

Specifications

Specifications

5′ x 8′ – 3500# – Utility Trailer Plans

  • 5′ x 8′ nominal bed size.  Actual bed is a little larger so it will carry a full 5′ x 8′ payload.
  • Single axle, leaf spring design.  Your choice of straight or drop axle.
  • 3500 lb. trailer capacity which includes the trailer and the cargo.
  • Construction is steel, welding, with a mix of common Tube, Channel, and Angle for an easy, sealed frame build.
  • Plans include many options to make the trailer perfect for you.  Use these options, or add your own.
  • Options like a Convertible Tailgate, a Removable Ramp that stores under the bed, and several possibilities for sides are all there.
  • Trailer weight will vary depending on design options, but will range from approximately 600 lbs (minimal flat bed) on up.

More About The Design Features

More About The Design Features

Design options in the plans help customize the trailer to meet your particular needs.  Things like a top, sides or tailgate add function if you want.  Extras like a motorcycle stand, a ramp and toolbox mounting can also make the trailer perfect.  Also read this article about customizing.

  • Trailer bed size is slightly larger than 5 ft. wide x 8 ft. long — long enough to lay 8′ sheet goods down flat, then close the tailgate.
  • At Mechanical Elements, we have changed the design paradigm.  We measure the trailer based on the cargo to carry rather than the outside dimensions.  That means you can put a 5′ wide item in, even with sides, then the same is true for the 8′ length.
  • Overall length including the tongue is ~146 inches.  (May vary with some options.)
  • 5×8 trailer plans show a deck height that can range from 17 inches up, depend on design options chosen.  (Bed height in the images is ~19″.)
  • Max capacity is 3500 lbs.* set by the axle, which includes both the trailer and the cargo.
  • For more information about building a trailer, please see the Mechanic’s construction tips and advice.
