I think you may be trying to shoot for too much. You may have to come up with a compromise.

A full size truck chassis will likely have too wide of a track width to tuck the wheels. For a lowered 4WD stance, an S10 would be a better choice; however you may not get the towing capacity you’re shooting for.

I’ve research bagging my S10 RWD chassis quite a bit though I’m no bagging expert by any means. But I will say that I think it may be more challenging to bag any Chevy 4WD. 80’s Chevy 4x4s had solid axles with leaf springs, then they went to torsion bar suspension, now they’re using coil over type suspension.

You said it, not I, that you're a n00b. Do you have any previous design / fabrication / welding experience? Swapping a chassis is not as simple as slapping a body on a different frame. There's a lot of work involved.
