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.

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
