Just responded to your IM you sent me, and now I came here..
Looks like you've got some work ahead of you if you're doing a complete restoration. Am I correct in guessing the suburban was restored at one time in the past?

Also--your roof issue is concerning on the driver's side--have you checked the front eyebrow area yet over top the windshield? You'll be fabricating that upper door frame area for certain. Also--check to see how bad the water damage is as you'll likely find the caulking around the perimeter roof seam is dried and cracked allowing that damage to start.

Also--the rockers are basically a two-piece job. The inner rocker/floor piece and the outer rocker are separate and joined with spot welds. In order to get at that area you've posted pictures of you'll have to remove the outer rocker (good luck saving it...) and work out out from there. As I asked before regarding it possibly being restored previously--you need to really start checking to ensure there was no half-ass covering of rust. Check the area around the front cowl vent area on the firewall as my suburban which came from northern CA had bad rust there, along with the roof rust you are getting to enjoy.

Good start to your project.
