Aren't you don't with it yet??

Still working on it but made a lot of progress this week...

I started on the dump box this week, its u shaped aluminum wall and floor Im using styreen for the side detail,door and bulkhead. A roof gaurd will be made after i know where the exhause stack will locate.Side boards will locate on top of the walls and a small spread pan at the rear. I used spring shackles to mount the box to the rear of the frame rails.
The bed sits on its own 20mm tall aluminum rails and will give proper clearancefor the rear axels

The lift tested good nd you can see the box has plenty of angle. I will be crossing my fingers it will lift a full load of dirt? If not i may have to revisit the lift as i still dont like how all the levrage is lost due to how far back the lift unit installs. I can't move it forward as it will interfear with the forward tandem. The drive has a u joint and the Carson lift motor is solid mounted in the truck frame rails.

I fabricated a box that will hold the battery over the motor/transmission. It's held to the frame with 4 screws so I still have easy access to the motor. A few rubber bands will keep the battery held down tight to the box
This will leave the floor space for the reciver and esc. I want as much weight over the steer axel to help with steering when its hauling a load. The cab will tilt from the front up and out of the way for access to changing the battery or electronics adjustment.

I made a cab visor and started fitting a air cleaner. The battery boxes are made and just need to mount them next to the fuel tanks.



I also got my driveshaft support bearing in and was able to test the rolling chassi for the first time.










Thanks for looking

I took the lift out tonight and tried a few things and I still can't get it further forward. I think longer arms may help but how this thing is designed I can't move the mounting of the lift any further forward. So even with longer arms it still will be pivoting in the same spot, thus longer arms will decrease leverage..... I will just have to test it out soon..


So after all that I kept working on the cab and box....I mounted the battery boxes,stack and trimmed the roof for cab lights. My next issue will be a front bumper...I'm going with the look of a steel bumper I started with plastic but I think I want to put a nice pice of steel up front I case I run into something... These old Mack's were bullet proof so I'm going to keep it in true form.

I test fitted the air cleaner and mounted the dog on the hood...after I get everything fitted I will think about paint...

Im not sure I like the budd rims on this truck. I was looking at spoke rims on eBay but they were the same ones as rc4wd sell and in my opinion don't look good...has anyone made good looking spokes wheels?
