Agreed. I had to get beaten down a couple notches on this one. Some things are best done with better bones. If you’re going that heavy get a bigger frame setup with the correct body mounting to avoid anything structural. Your wallet will thank you. It’s one thing to have the donor already with these trucks and do a “just for *****” build but it gets over budget really quick when you start seeking out in demand and expensive parts for themSell the 1500 and get a 2500/3500 crew cab. That solves some of the issues.
You need to raise the cab to fit the Allison.
You won't be able to run the Duramax setup with your wiring harness.
And the SAS by itself is really involved.
In short, probably best to buy a GMT 800/900 Duramax and do a SAS (SAS on that generation seems easier than gmt400 from what I've found) or an F250/350 4x4.
