Bagged c10 dually

[outlawmatt]

So I got a 67 c10 that this guy was going to just scrap and I decided that I wanted to do a bagged project for once, right now it has leaf springs and sits completely stock with no bed. I have a 350/400 setup ready to go in and I have a dually rearend that I can use as well, now I want to bag this truck to lay as low but not lay frame, and still pull a 8klbs gooseneck that's 40' long.
I don't want to take the truck on long drives but just around to local shows and tows that I have to do around town.
I the suspension from a coil spring c10 to use as well.

What is the safety of the bags if I were to put them on?
Will I need to put 4 bags on the truck to support the weight?
Boxing in most of the frame and adding cross members?
Im not planning on c-notching the frame, but maybe moving the axle closer to the cab to use the arch in the frame that's alreadyt here.


I guess I'm asking is this going to be safe and ok?

Considering bags are used in 18 wheelers

You will just need to use the appropriate sized bags for the job
