I think I've bought a couple sets from you engiaruph...
I did them in my 2011 Extended cab and 2004 Suburban (both since sold). Not the cheapest option but great quality and can be done in a weekend at home with patience and band-aids: The metal from the seat frames is not nice to fingers.
2011 Black was a cloth to leather upgrade and the 2004 was a kid filled 200k mile interior redo.
I pulled the seats in the 2011 since they were manual and left them in the burb since there was a lot of wiring to mess with. Easier to do out of the truck for sure but not too terrible in the truck. You'll need basic tools, a heat gun, patience, and the willingness to trim brand new leather with a razor!
Here's a pic of my 2011 black with grey suede inserts and red contrast stitching.
