Repair Manuals

I have searched hi and low for a Chilton type manual for my 2001 2500HD with a Duramax but come up with squat. Does anyone have a recommendation for a decent repair manual for these vehicles? Found one easily for my wife's 2001 GMC Yukon but not these. Any ideas?

Regards,
Mike

Either of these are the same, exact source the dealer shops use. Anything else may leave you wanting. I use Alldata. It's an online subscription service, but contains all the same data as the Helm manual, at a fraction the cost, especially if you need it for several vehicles.
