8.5′ x 12′ Deckover Trailer Plans – 7000 lbs – Single Axle

Description

The smallest of the Endurance Duty family, these 12′ Deckover Trailer Plans boast a 7000 lb. Single Axle (with option for 8000 lbs.).  BUT it is not small, and it is not light duty!  Check the specs in the accordion tabs below, because the Deckover trailer in these plans is a workhorse.

Even with the smaller size, we still offer all the excellent options – like ramps, hitch style, deck style, various sides, and more.  Even the options have options – like choices for ramp length and strength.  See some of the options in the images above.  We say “Make it the way you want it.”

Single Axle, 7000 lbs, 12′ Deckover Trailer Plans

If you want a full width, flat deck, but don’t need the length, this trailer is your ticket.  With a 12′ deck and a single axle, it will also be easier to manage – both to use and to store.

Smaller does not mean less.  These trailer plans include the same Trailer Design and Engineering for a long, robust life.

Because of the smaller size, and to make acquisition of parts easier, this trailer has a slightly wider axle in a more standard width.  Rub rails and stake pockets are available, but not the base design.  Additionally, the tail plate is not a special made large part so things on this trailer are a little easier than on some of our larger deck-over designs.  All this by request of customers like you.

More About The Design Features

While the specifications are nice, here is little more information to expound on the trailer features.

• * The trailer is 8 feet 4 inches wide (allowing D-Rings to be added to the sides and still be within the typical legal width limit).  Option on width to include the rub rails.
• Deck length is 12 feet 1.75 inches including the steel frame.  (Considered a 12′ Deckover Trailer.)
• Overall length with the tongue is 204 inches (17 feet) – which will vary a little with options.
• Trailer bed height will depend on design options.  Typical is ~34 inches, but will vary with tire size, spring shape, shims, load and other options.
• A single axle defines the trailer max capacity – which includes the trailer weight plus all options plus the payload.
• 4 axle capacities are specifically included:  5200 lbs, 6000 lbs, 7000 lbs (primary design), and 8000 lbs (which requires some minor changes noted in the trailer plans).
• Suspension is leaf springs, double-eye style.  Slipper type springs are acceptable.  See notes for conversion to torsion axle (also acceptable).
• Trailer weight will vary depending on design options.  The 7K base flat deck trailer is in the 1400+ lbs range, which includes the axles and wheels, but without decking, sides or ramps.  Options like sides, decking choices, and all the other options will change the weight.
• A full plank deck (made from 2×10 lumber), including steel cover plates over the wheels, will weigh between 500 lbs and 600 lbs for this 12′ Deckover Trailer.
• Deck options include material type, connection options, with or without the wheel covers, etc..
• Build the standard flatbed, or choose on of the sides options – permanent or removable – also 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.
• Design includes options for a raised front rail (or not), and a tongue tray for special tools (or not).
• Choose a mounted toolbox, a tongue tray, spare tire, etc. are there for optional functionality.  Since some options are mutually exclusive, not all options are in the pictures here.

  

• The download package includes the detail drawings, the illustrated instructions, plus a few CAD files for laser or water jet cutting some of the sheet parts (like the wheel covers and optional tongue tray).
• 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.  Enjoy your build.
