Just bought this motorhome with the 8.1L engine, and am trying to catch up with maintenance on it. Bought it with 19K miles and it seems to run great, however, never knowing how the PO treated it, keep finding little surprises. After having the dog house off the motor and doing a little more...

I have an 02 2500HD, swapping the motor out next week with a younger 8.1, any recommendations on a cam for towing, sometimes 10,000 to 12,000 lbs. ?
