Description

Description

This is a heavy duty trailer.  At 14K or 16K by 20′ deck length, this deck-over trailer is a workhorse.  The plans are fully engineered and ready to build.  Like all our other Deck-Over trailers, these blueprints have several options and extra features you won’t find with our competitors.  The frame is engineered with structural steel – option for 14,000 lbs or 16,000 lbs – then you choose the rest.

Choose options like ramps, hitch, deck material, sides, and more.  Also, the options have options – like choices for ramp length and strength.  Build it the way you want it.  This trailer is tough by design, with the engineering to back it up.

Tandem Axle, 14K or 16K at 20′ Flat Deck

When you need a really beefy deck-over trailer, there’s not much else to substitute.  The trailer deck is 8′ 6″ wide by 20′ long with tandem axles to give 14K or 16K lbs capacity.  Yet, it’s not just beef, there’s a lot of finesse beyond base trailer.  Plans include options, and options in the options.  Need ramps just a little longer or a little stronger?  The plans give options for ramp length and strength, so you can find your sweet spot.

Choices let you build it the way you want it.  We engineer it for robust action, then you build it and enjoy it.  In researching other deck-over trailers we found many niggly things some owners would change.  That brings us to add options, then you can make the decisions.  Since it’s from Mechanical Elements, these are things to expect.

Deck-Over Trailer Plan Options
Some of the options.  Plank deck, 8.5′ Ramps, Perimeter Rub Rails and Stake Pockets, Front Stop Rail, Tongue Tray Storage (hard to see), Pivoting Tongue Jack, Adjustable Hitch, and 15″ wheels.  Many options exist.

  • Overall length with the tongue is 302″ (a little over 25 feet) — will vary with some options.
  • Trailer bed height depends on options.  Typical is ~35″ to 36″, but varies with tire size, spring shape, shims, load, etc..
  • Option for 14K or 16K (16,000 lbs) max capacity (combined axle rating)* using tandem axles — rated at 7000 lbs or 8000 lbs each.  Load capacity includes the trailer weight with all options, and the load.
  • Of course, the suspension is heavy leaf springs, slipper style, with equalizer.  Not made for independent torsion axles (see this article).

  • Ramps are an option — Choose ramps that slide in (and store) under the deck (or not), then choose ramp length and capacity.  The engineering is there to help you choose.
  • Design has options for a raised front rail (or not), and a tongue tray for special tools (or not).
  • Choose a mounted toolbox, spare tire, etc. for functionality.  Since some options are mutually exclusive, not all are in the pictures here.
