I added some 1/4” x 3” flat stock to make the top of the rails in the rear all in the same plane, which will be important for when the dump bed is in place.

After that I worked on boxing the frame further forward - this was a lot of work, starting with getting the frame rails all the same width and straight, after that was done I made a pattern to transfer to the 1/4” plate to cut out with the plasma, then once the plates were cut on the plasma they needed a lot of trimming to fit correctly. The next piece in front of that was much easier since it was just a simple rectangle.

The next section of the frame has all kinds of different shapes and thicknesses, so that’s going to be very tricky to execute.
 
Today I started out by making the filler pieces under the rear cab mounts.

Next up I removed the motor mount pads and engine crossmember so I could clean them up with a wire wheel. Once they were clean I reinstalled them and then welded them to the frame.

Once that was done I started working on boxing the frame some more. I took a while to evaluate the frame rails and then trimmed them so the contour was workable and consistent. With that done, I made a template to transfer to the steel plate. Unfortunately, the piece didn’t conform to the frame rail as nice as I wanted and I had to make a relief cut…..it still turned out pretty well though. On to the other side tomorrow.

That frame isn't gonna have any flex to it! it's gonna be stout but if you do any off-roading with rocks I would think the truck will be teeter-tottering between the front and rear opposite wheels
Nope, shouldn't be much flex - just what the suspension wants to do, which I think will be appropriate for how this truck will get used.
 
Yesterday I got the boxing plate next to the motor mount on the passenger side made and installed, but forgot to take a picture. I managed to get that side installed without a relief cut, so I was very pleased with that.

Tonight I spent most of the evening making sure the frame was flat and supported well in the front so I could remove the upper shackle hangers for the front springs. I needed to do that so I could get ready for boxing the frame in that location. After that I got the frame trimmed how I want it so the shackles will clear the frame once the boxing plates are installed. With the funky contour here, I’m planning on doing each side in 3 pieces.

for a bare frame, it's not difficult to electro-plate it once's clean and oil free. you just need a BIG tub the submerge it into the water mixture with the chemical for the plating. attach a pos and neg from a battery or some other power source. iirc you hang a pos lead in the tub and connect the neg to the part you want to plate. I could be wrong, but there are a ton of videos online for how too's

once plated, paint or powder coat it 😁
 
At work, we send our products to a place in Indiana to have them dipped in e-coat. It's the same factory that e-coats Hummer frames (or at least it was the same place, but it's been about 15 years since I visited). Right now, they charge us about $17/foot to dip product in baskets. I don't know if that rate would also apply to something like a truck frame or not. However, I didn't go into the boxing with that in mind, and so I didn't clean the frame on the inside like I would have if that was the plan. I think the cavity wax and drain(s) should be a sufficient strategy for this truck. I will probably also try to plug as many of the factory holes as possible to reduce the methods of ingress for dirt/mud/debris, though there will still likely be large openings in the front and rear of the frame rails.
