Introduction: Custom Flatbed

I normally start all of my projects like this in a 3d cad software and make a full plan, multiple times. and this one I made probably 4 different plans for and didn't like any of them, so eventually I just pulled off my old utility bed and just built it as I went.

This will be more of a picture documentation because I really didn't have a full plan on how to make this. But hopefully you'll be able to get some ideas from this, and if you like my design make one similar.

Step 1: The Building Process

Let me start off by saying this, i bought this truck for $500. although I've rebuilt the engine and transmission, the chassis still has nearly 280,000 miles on it. I will be the last owner of this truck because I love it and will continue to drive it until the day it rusts apart falling to pieces where it sits.

Because of that I decided to go ahead and weld the flat bed directly to the frame. I WOULD NOT suggest this for anyone else. there are multiple bolting points on the frame that you can use with the typical pucks to bolt the bed to the frame. WELDING DIRECTLY TO THE FRAME WILL COMPROMISE THE STRUCTURAL INTEGRITY OF THE FRAME. That said, to keep a low profile and mount the bed exactly where I wanted to place it I went ahead and welded it directly to the frame. That also allowed me to create a pocket in the middle of the bed so I can create a slide out drawer for tools and a set of motorcycle ramps that i can keep in the bed.

Step 2: Decking

I used metal bed frames for the angle iron to use as the cross bracing and supports for the 2x6 tongue and groove decking. The framework that goes above the truck is going to be used to hang my light bar directly below it, and will be able to be used as a materials rack once I build a second removable one for the rear.

Seal the decking with a stain and water resistant sealer.

Step 3: Add a Load

I've thrown some pretty heavy loads on my bed, everything from motorcycles to trees to huge loads of dirt and gravel. The flat bed has held up well and has never struggled to hold anything I've put on it.

Thanks! I haven't had any issues with the wheel hitting the bed. I measured the amount of travel that the axle had and then added 3 or 4 inches. That's why the cutout is there in the bottom frame so that I can keep the bed as low as possible without worrying about the wheel hitting it. The fuel filled neck is actually just zip ties right now but I plan on welding a piece of plate metal in between two of the trusses and mounting it there when I get some more time. That's why I haven't painted the framework yet. All in all it only cost me about $80 because I had the metal left over from other projects. But the 1.5" tubing would be about $200 if you needed to buy it yourself. It's not very heavy guage.

Thanks! You got my vote, by the way.

Looks really good! Tell me, have you had any issues with wheel bounce, i.e. the wheels striking the deck on rough terrain? Also, did you seal the the frame of the flatbed? Additionally, what was your total overall cost for this project? Once again, really good job.

Also, what did you do about the fuel filler neck?
