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, and the correct lengths and widths etc. 

This gorgeous Kenworth W990 pulling one of my 53′ triaxle drop decks owned by Timothy Nicolau out of California.  He took delivery of this trailer Nov. 2022.  Beautiful rig! I am jealous of that Kenworth!

Here is the gorgeous rig owned by Ryan Blake of southern Idaho. I just finished another 53ft drop deck for him in APRIL 2020, and what an amazing setup he has!!

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

    Need to buy one of your trailer s 42yrs driveing retire now with 1)14 scale Tamiya truck no tralier looking for to buy flat bed 48 102 thanks

  5. Rubin says:

    Please email me your price list, Moreover will your trailers fit a Wedico Peterbilt?

    • Darwin says:

      Hello Rubin, I am not sure how well they fit a Wedico, my trailers are 1/13.5 scale which is what Tamiya is actually. So the width of my trailers are 7.55″ and they sit level with a 5th wheel height of 4″ which is what a stock Tamiya truck is. What is the outside to outside width on the rear tires? 1:1 102″ wide trailers overhang the tractor duals by about 3″ on each side, so on a Tamiya that equates to a .22″ overhang on each side which is what my trailers do. Let me know the trailer you are interested in and I will get you a price. Thanks, Darwin

    Thank you, Wes

    • Darwin says:

      Hi Wes, I don’t build low boys, thank you for inquiring though, I appreciate it.


      • Steve Bridges says:


        I am interested in pricing on, and I hope I get the description correct, the 48 or 53 foot drop deck, tandem split axle with the tool boxes between the tandems. I am hopeful that I am able to afford one of your tremendously correct works of art. I have been wanting one of your trailer for several months but an 87 day hospital stay threw a wrench into the works for a while. Whether I am able to afford one of your custom trailers or not I still have to say if they are half as good looking as the pictures I do see them as a tremendous work of functional art. I am probably out of my budget range but I have to ask about pricing where I can see if I can find a way to purchase one of your trailers.

        No matter the outcome I am truly in awe of the work you are turning out.

        Best Regards,

  25. Paul Serna says:

    Your work is excellent! They look spot on! Have you ever thought about doing a Conestoga trailer?

    • Darwin says:

      Hi Paul,

      I actually did make a prototype of a rolling tarp system a few years ago, made the aluminum tarp supports, track and wheels and tarp.It worked pretty good. I had it fitted onto the Tamiya flatbed to see how it would work. I was going to make a short version before I went to all the work on making it on the fullsize trailer. But that was as far as I got, put it on the shelf and there it sits. Maybe someday……

  26. John says:

    Darwin the trailers look fantastic. I’m looking for a price and availability of the 48′ split axle with the tool box. Also do you make any other trailers (53′ box)?

  27. Walter Hardaway says:

      Thank you Walter! Wow, 40 years! Congrats!! Look forward to doing business with you, we can get you set up with the right trailer for some armchair trucking!

  28. Melissa says:

    I bought my boyfriend a grand hauler rc truck to build. Which he did and it looks awesome. Now that it is done he would like a trailer. Your trailers are so beautiful. I was wondering for the first photo how much the drop deck beaver tail is? With the lights, box. Would you be able to do one with ramps that go down? I have a little mini revo rc be so cute to drive it on it. Have the truck drive it around. Is it possible to have wood on the deck instead of metal. I like the look of wood. He said if I get it I can have it the way I want 🙂
    Thank you for you time!

  29. Doug Long says:

    Hello, I would like to get some prices for a custom flat bed trailer.
    I want to build a custom semi and flatbed trailer that replicate my dad’s truck and trailer in memory of my dad.
    I am looking for a flatbed spread axle with lights, I do not want the side boxes.
    Here’s where it gets a little confusing, his flatbed was a 42 foot 9’1″ spread axle. How close can you get to that length? What would the trailer cost me.
    Thank you

  30. Jason allen says:

    Do you build any closed tandem flatbeds? If so what the price with shipping?

  31. Gary says:

    What’s your prices on your 53 / 48 flat deck and do you build other types of trailers or just flat decks

  32. Brian says:

    hi is it possible send me your price on the B- Train and your 48″ Spread

    • Darwin says:

      I will send you an email, but as far as the Super B-train set goes, I only made one of them and my father bought it to display in his antique store. It is sitting on a shelf there. I did ask him today if he wanted to sell it because someone else was also interested in it. He said he might 🙂

      Thanks ,

      Thanks, I appreciate the kind comments! I have heard from a few people who were there and saw my trailers. Wish I could have been there. Maybe next year. I sent you an email, but I should be set back up in my new place in September sometime, and be back building late September. I have already taken some orders for October, I think some of them were at the show! Very happy everyone liked the trailers. That’s what it is all about.
