I have the 4 book set of the factory GM service manuals for a 2003 model year Escalade. Covers the Suburban and the GMC models too. I also have the Chilton and the Haynes manuals which i will include as well, which covers the platform too, even though they don't specifically say they cover the escalade. All in very good shape!
