At such a great size, a 4×8 utility trailer is perfect for odd jobs, fetching lumber, light landscaping needs, or for hauling a motorcycle. This is, one of our most popular sizes. At 2000 lbs capacity, this trailer is tough for the work, yet relatively light and easy to pull – even behind a smaller vehicle (see your vehicle specs).

4×8 Trailer Design Details

4x8 Utility Trailer Plans – Excellent DIY Project – 2000 lbs Capacity (4)Plans include easy to follow, instructions (with illustrations) and construction options. They also include a parts list with suggested places to purchase the components.

More About The Design Features

Because you should know, here is a little more information about the 4×8 Utility trailers made from these plans.

  • Trailer bed size is slightly larger than 4 ft. wide x 8 ft. long. Allows 4×8 sheet goods (like plywood, drywall, etc.) to lay flat on the bed.
  • Overall length including the tongue is ~150 inches. (May vary with options.)
  • Trailer bed height depends on options — from 16 inches up. (Bed height shown is 19″.)
  • Tires shown are larger than needed for aesthetic purposes. Certainly, smaller tires, fenders, etc., are acceptable.
  • Max load capacity is 2000 lbs.* which includes both the cargo and the trailer.
  • Also, please visit the Mechanic’s construction tips and advice for more ideas about building a trailer.

While the animated image below is actually of our 4 x 6 Utility Trailer, these trailer plans include all the same options — just with a longer trailer bed.4x8 Utility Trailer Plans – Excellent DIY Project – 2000 lbs Capacity (5)

These trailer plans are for a traditional leaf spring suspension. If you prefer, we also offer similar 4 x 8 trailer plans designed for a torsion axle. Leaf springs are less expensive and much more common, while torsions offer some ride improvements. We also offer plans for a 3500# capacity 4’x 8′ Utility Trailer.

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.

Thank You — The Mechanical Elements Team
