06 Tahoe body lbz chassis

If you're up to the frame mods, brake lines, parking brake, adding the additional body mounts, etc. then using the truck frame is a good way to go. It'll be bulletproof for towing/payload that way vs. the 1500 Tahoe.
If you want to be lazy, get the wife a 2500 Suburban. That's basically a bolt-in. My brother and I built my Duraburb with a 2500 Suburban and it was cake. 2 weeks start to finish over Christmas / New Years. You lift the body off, remove the original engine/trans/TC, swap motor mounts on the frame to the diesel ones, move the trans crossmember back ~1", new rear driveshaft, use stock truck front driveshaft, 2" body lift (Suburban frames don't have it built in like the trucks), and some fuel plumbing. Electrical is documented various places, just swap some wires around and use the Suburban fuse block (so the rear AC and all that still works).
For your Tahoe plan, it is much the same, but with more frame work. Electrical will be the same, and just put the whole front clip off the truck onto the Tahoe body (fenders, core support, hood, etc.).
For the ABS and other modules, it is not as hard as it sounds on the GMT800 platform. Every module has the VIN stored, but only 2 modules use it for anti-theft. The BCM VIN is considered the "master" VIN.
Overall, what I like to do on modules is to leave the BCM VIN matched to the Tahoe, then update the VIN in the ECU to match the BCM/chassis as well, but that isn't necessary. The ECU uses a seed/key setup for security that can be learned even with a VIN mismatch. But it is often simpler for smog checks if the ECU VIN matches what is on the door card, and you are almost certainly going to want a tune anyway.
Good luck on your project, a Durahoe sounds like a fun thing!

- The high-end touch screen radio compares its VIN to the BCM, and won't work if it doesn't match. Just do a theft relearn with a Tech2 and you're good to go.
- The XM radio receiver does the same comparison, but no way to reset it. Easiest is to keep the XM and BCM as a matched set, or you can send the XM box off to get opened up and reset, but it isn't super easy to do.

So I kinda changed my plans a little, and decided to go with a single cab long bed frame, and just move axle forward and cut rear frame section off. Bought this gas truck at an insurance auction it'll be here tmr some time. Been looking for another Tahoe body, after looking into hers more the rockers are starting to rust out, so trying to find a decent 2wd or something to use the body from, and that way I don't have to down her only dd. Slowly but surely I'll keep gathering parts and hopefully come summer I'll be ready to get started.

2500 Quadrasteer Suburban solves that :woott:
Keep with the Tahoe if that's what the wife wants. A 2500 Tahoe will be one of a kind.
