Project 42213 Unimog Mods and Attachments

[Paul B Technic]

I’ve always been a big fan of LEGO Technic Unimogs. My love for them goes back to set 8110, which I used as a base to build a wide range of attachments a few years ago. Since then, I’ve enjoyed creating various multi-function off-road trucks—mostly Unimogs and similar trucks—where I could experiment with designing and building attachments to extend their functionality.

So, when I discovered that the LEGO Technic 42213 Ford Bronco had a C-model designed in the style of a Unimog-type truck, I knew right away that it would make an excellent base for further modifications and attachments.

Front Modifications

One of the first changes I made was to the suspension. I added a 5L black beam across the front. While this may look like a small adjustment, it’s actually quite important—it creates a sturdy mounting point for front-mounted attachments. This is going to be the connection hub for tools and add-ons, making the truck far more versatile.

 

 

 

 

Rear Tray Improvements

On the rear, I modified the tray by removing several of the flat panels. These were replaced with Technic beams, which give the tray a much more solid structure. The main benefit of this change is that it allows rear attachments to be added or removed with ease, and the tray itself can better handle the stresses of heavy loads and mechanisms.

 

 

Stronger Lifting Mechanism

I also reworked the tray’s lifting mechanism. Originally, it tended to flex when raised to its highest point. With my modifications, the lifting action is now much stronger and stable. This makes the truck far more reliable when using the rear tray for functional builds.
 

 

 

Looking Ahead

While these changes technically go beyond the “official” C-model—since they require extra parts—the overall look and style of the Unimog remains the same. That’s important to me, because I wanted to preserve the truck’s character while boosting its playability and strength.

This Unimog is now set up to be a fantastic base vehicle for future attachments, and I’m really looking forward to designing a range of front and rear tools to pair with it. Much like with my earlier 8110 projects, I see this truck becoming the heart of a new system of interchangeable Technic builds.
