1/14 Scale CoastWay Aluminum Trailers

1/14 Scale Custom Aluminum Flatbed Trailers

I designed my own line of flatbed trailers called CoastWay,  to fit Tamiya’s 1/14 scale trucks, such as the Grand Hauler, King Hauler and Knight Hauler. The main reason was because I didn’t like what was currently available on the market, most of them were not to the correct scale.

I have designed these trailers from the axles up, including the axles and airbag system. I designed my own DOT bumpers and frames as well. The only thing on these trailers not designed by me are the wheels and support legs.

One of my goals was to have these trailers look scale in their appearance, which was hard to find with the stock Tamiya trailers currently available.
This meant the correct height between the underside of the trailer and the
tractor tires. 

This is a 53ft flat deck spread axle trailer I just completed, 1-30-19,  and shipped to my customer, John Nanartowicz, who has it hooked to his gorgeous Freightliner tractor. He just sent me these pictures. Beautiful rig!



Just finished a 53ft drop deck tri-axle in May 2018 for Ryan Blake in southern Idaho, here is the trailer behind his beautiful truck!

Just finished a couple of 53′ drop decks this last week. Nov. 2017.  Stacked them on the 53′ quad axle and they are ready for delivery.

Many trailers currently offered on the market sit much too high,  which I didn’t like.  The reason they all sit too high is because of the automatic 5th wheel couplers attached to the 5th wheel plate.
My trailers support legs work just like the real ones do. They are manually operated which means no thick auto coupler making the trailers sit way too high. I have never operated a 1:1 flatbed semi trailer that automatically snapped the landing gear up when I backed under it in real life. They are all manually operated.

It also meant the correct width overhang for a 102″ wide trailer. Full size 1:1 trailers overhang the tractor duals by 3″ on each side. My trailers overhang a Tamiya truck’s dual wheels by .22″ on each side which is scale.

My trailers are built to 1/13.5 scale which is what 1/14th Tamiya semi tractors actually are.  I have tried to build my trailers to scale in width, height, and length, based on a full size trailer’s dimension of 48′ long and 102″ wide.

All my trailers come with led marker lights and led taillights and hidden wiring .  Wiring is completely enclosed between the the two decks along with an enclosed battery.
  The LED lights have their own 7.2 volt battery mounted in between the frame rails in an aluminum battery box with a toggle switch. This makes for a very neat and clean underside. Trailer lighting is independent of the truck, trailer will have marker and taillights regardless of what you have on your truck.
Note: Battery is not included in price.


The suspension is a modular air bag trailing arm design.  Its design also makes it easy to transform one of my trailers from a closed tandem trailer, to a spread axle, or even a triple axle trailer.
It is just a matter of taking a couple of bolts out and sliding the modular suspension to where you want it mounted, and for a tri-axle simply add another suspension module between the existing spread axle units.

Independently turning axles are housed in an  aluminum axle tube assy. with pressed in bearings and bushings



Trailers are built out of 100% aluminum, including the wheels and the black anodized aluminum support legs. The only thing not aluminum are the nail strips on the deck. All hardware is metric, low profile hex head hardware where possible.

 Under deck Aluminum tool boxes are all aluminum and feature opening drop down doors They are available in two sizes, the smaller size fits the drop decks and the larger ones are for the flat decks


Trailers come with DOT  safety tape on the sides and rear. You won’t find these trailers anywhere else as they are all my design.

48ft Trailers measure 42.80″” long and 7.55″ wide, which is based on a 1:1 trailer’s dimensions of 48′ x 102″.

53ft trailers measure 47.25″ long

    Hello I go by the name Tony,I love your work.I wanted to know if you possibly did 1/25 scale

    • Darwin says:

      No I’m sorry I don’t. I built one 1/25th scale drop deck 13 years ago and that was the first trailer I built. Then I moved to 1/14th scale. Thanks for asking and I appreciate your kind comment!

  2. Cedric Wesley says:

    Hi. Do you have any 48 foot drop deck beaver tails or 53 foot trailer already ready or how long is the wait for you Build one?

    • Darwin says:

      Hello Cedric, I am taking a break over the summer so I don’t currently have any trailers in stock. I only built the one beaver tail but I have had a lot of people interested in them. I may make a small run of them starting in September. The reason I didn’t make any more of them originally was because they were a lot more labor intensive and more expensive than the straight drop decks and flat decks. I may put a post out in a day or two and see how many people would want one. If I make more of the beaver tails they will come with folding ramps that will make the back of the bed flat when they are folded up.

      Thanks, Darwin
