Bagged and bodied 99 c3500 build

Say whats on your mind, feedback, good or bad is why im here. They are a bit heavy. Not sure if it's too heavy or not.
I have seen that done multiple times, I am trying to do something that is different, in no way am I saying it's better or even the right way to go.

It's been done that way multiple times because it's strong. You have a lot of flat stock laid in a way that doesn't use its stiffness.

Keep in mind that I'm not an engineer, so this is my best guess as to what sizes you would need. When I first started typing my response I was thinking half-ton, and in that case I'd probably go with 1.5"x.120" tubing and a single piece of 1/8" plate in the middle. Re-reading I realized it's a dually. With that in mind I'd go with 2"x.120" tubing and a single piece of 3/16" plate in the middle, or if you want it really strong, weld two plates of 1/8" plate to the outside edges. With two plates it will probably be approaching what you've made for weight, but it will be far stronger.

Having a larger single plate in the middle allows you to cut lightening holes. They eliminate a significant amount of weight without reducing the strength of the part.

I get what you are saying, also I'm no engineer but I have made allt of things. I'm confident that what I made with the interior bracing and boxing things in will be more than strong enough for the job it has to do. I do really appreciate your opinion and knowledge.

Some real progress today, getting the rear of the frame all tied into itself.

It's from an 08 buick lucerne. Hands down the most comfortable seats I've ever sat in.

They sit about the same height as the stock 60/40 even when I cut down the risers as low as I could and still clear the trans hump.
