I purchased a 2001. 5, 3500, 6X6, 6 speed in late Mar. of this year. To make a long story short, I have a 1999 service manual I would like to give someone if they would e-mail me their address. I have since ordered a 2001 service manual for my vehicle and have no use for the 99 manual. The 99 service manual is one {1} volume. I have learned so much logging in as a guest and since becoming a member. I would like to thank each and everyone for their knowledge and information. You are no doubt a great bunch of guys. Philip.
