I finished another new design tonight, and this time it's a 35' East dump trailer. I had a lot of components to start from, so the design time was significantly reduced. This will look nice with a daycab Pete or Kenworth. This is a triple axle version, and it was designed with all 3 axles on the ground, but it can easily be modified with the front axle in the raised position. It's pretty bare bones as is, and could use a tarp if desired.
This is a MAC trailer pictured here, but I like the combo a lot. It definitely gives me some ideas.
