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

Technical Details — 16K by 20′ Deck Trailer:
- * The trailer is 8′ 6″ wide (typical legal limit), with a 20′ 3.5″ bed length (including the frame). 8′ 6″ width includes the rub rails.
- 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.
- Suspension is leaf springs, slipper style, with equalizer. Not made for independent torsion axles (see this article).
- Trailer weight depends on options. The base trailer plus decking choice, sides, ramps, accessories, etc..
- Plans have many options. Here is a partial list.
- Deck options — material, connection options, with or without the wheel covers, etc..
- Build the standard flatbed, or choose sides — permanent or removable. And, sides options have options like tie-downs, rub rails, stake pockets, etc..
- 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.
- Blueprints include the full set of drawings, illustrated instructions, plus CAD files for laser or water jet cutting the tail plate and special parts.
- We give plans the way we would want to receive them. Complete, with details and lots of info. Some you’ll use, some not, but we give you choices.
Tandem Axle, 14K or 16K and 20′ Flat Deck:
When you need the broad, full width deck, there’s not much else to substitute. The trailer deck is 8′ 6″ wide by 20′ long with tandem axles to give either 14K or 16K lbs capacity — making this Deck-Over stout. Yet, there’s more than just the base trailer — there’s options, and variations in the options. For instance, our research shows many owners wish their ramps were just a little longer — so our plans give options for ramp length. Other owners complain the ramps are not strong enough — they bend! So, we give options for that too. And, we include a chart with capacity by length so you can find your sweet spot.
Giving choices let’s you build it the way you want it — which is the Mechanical Elements way. We engineer the design for robust action, then you build it and enjoy it. In researching other deck-over trailers we also found that many side rub rails had damage. Yes, the rub rails did their job, but many with damage. The more robust trailers have thicker rails, so this design includes a nice balance of thick and wide — and you can choose. The same is true throughout the trailer. Since it’s from Mechanical Elements, these are things to expect.
More About The Trailer Plans At Mechanical Elements:
All our trailer designs include Strength and simplicity with standard beams, gusseting and triangulation for rigidity. They are strong, by engineering and design, starting at the frame, and they do not rely on sides to meet capacity. Yes, sides options are included, but they are not required. The frame is a solid foundation so the trailer will perform and last.
Towing Stability, comes from engineering design fundamentals to tow easily. Though the plans include adjustable options for various load types, you can choose. Equally important is Maneuverability, so the tongue is long enough to give proper vehicle spacing.
Design Versatility is in the plans — with axle and brake choices, load and deck height variations, sides (or not), a top (or not), and deck material choices. Options include ramps or tailgates like a fold down tailgate/ramp combination. — All are in the blueprints and instructions.
Finally, there are options for Flexibility like a hidden ramp, motorcycle stands, an aerodynamic-ish front, toolbox mounting, infinitely variable tie-down placement, and more. Pictures show some of the options. While we encourage customizing, we also suggest these guidelines to think about.
Plans include complete drawings and illustrations with the instructions — and construction tips. They also have a parts lists and a materials list along with suggestions for purchasing components.
Reminder: Trailer construction requires metalworking skills and tools for things like cutting, drilling, accurate fixturing and set-up, as well as welding. Strength, durability, and enjoyment depend on how well the trailer is made. Build it well, then Enjoy the Finished Project !!
