24′ Gooseneck – 13,000 lbs Deck-Over Trailer Plans

Description

If you want the benefits of a gooseneck, but do not need a heavyweight, this trailer fits right in the middle.  These are plans for a 13,000 lb deck-over gooseneck designed with balance of usability, and everyday hauling.

The gooseneck improves stability and load distribution, while the overall design stays efficient and practical.  This is a great fit for builders who care more about how a trailer works than how high the rating sounds.

Engineering In This Gooseneck Trailer

A full flat deck is the beauty of a deck-over trailer.  We keep that, like our awesome similar size bumper-pull.  However, this design is purpose-built from the start as a gooseneck trailer.  (A gooseneck and a bumper-pull behave quite different, so they need different engineering.)

One of the first things to notice are the engineered gussets.  Some manufacturers have beautiful engineered gooseneck beams, but those are nearly impossible for DIY.  Instead, we created engineered gussets that are stronger and lighter than the big triangle plate gussets you have seen.  Read more about them in the engineering a gooseneck article.

This trailer is tough by design, and made for a lifetime of hauling.  No shortcuts, just strength, by design.  No shortcuts in the drawings either;  this plan has 65 pages of images, notes, explanations, instruction and detail, plus the instructions document with lists of materials, components, engineering considerations and more.  See specifications in the tab below.

We give you choices.  Choose your deck style, various sides (or not), ramps, rub rails, jack styles, tie-down locations, and more.  Even the options have options – like choices for ramp length and strength.  We do the design and engineering, so you can build it with options you want.

More About The Design Features

While the specifications are nice, here is little more information about the trailer features.

• * The trailer is 8 feet 6 inches wide (typical legal width limit).  8’6″ width includes the rub rails.
• * The trailer deck bed length is 24 feet, 3.6 inches including the steel frame.
• Overall length with the tongue is 33 feet, 2.6 inches – which can vary a little with some choices.
• Trailer deck height will depend on choices.  Typical is ~35 inches, but will vary with tire size, spring shape, shims, load and other options.
• 12,000 lbs axle capacity (combined axle rating)* using tandem axles rated at 6000 lbs each.
• Total trailer capacity is 13,000 lbs which includes the trailer weight with all options and the full max load.  This include 20% to 25% tongue weight (2600 lbs to 3200 lbs tongue weight).
• The suspension shown is leaf springs, double eye style, with equalizer; Slipper type springs are also acceptable.  This trailer is not designed for  independent torsion axles (see this article).
• Trailer weight will vary depending on the options you choose.  Weights for the trailer in the specifications tab (above) are estimates only.  The materials you choose along with the options you choose, will set the weight for your trailer.
• Many options are in the plans.  Here is a list, yet it does not include everything.
• Deck options – materials, connection options, with or without the wheel covers, etc..  The gooseneck mini deck is also an option.
• Build the standard flatbed, or choose one of the sides options – permanent or removable – shown in the plans.  Sides options have variations, including options for 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 the ramp length and capacity you need.  Engineering data for strength based length is included.
• Choose a mounted toolbox, an upper mini-deck, spare tire (and location), etc..  These are for optional functionality.  Since some options are mutually exclusive, not all options are in the pictures on this page.

  

• The download package includes the full set of drawings along with illustrated instructions and CAD files for laser or water jet cutting of the tail plate, the gooseneck gussets, and other option parts.
• We provide the plans complete, the way we would want to receive them.  We think they are much more complete and more detailed than any of our competitors.
