[Keep on Trucking]

Well I am a big 6.5 turbo fan. I know it is not even in the same class as a Cummins or Power stroke, but they do have thier place. I am actually working on my own web site right now that will cater mostly to the 6.5 td. I sell a bunch of the PMD extention cables for the 94&up trucks.
If you are going to pull serious loads alot the Cummins is the way to go, but in a Suburban I would go with the 6.5, it will just about fall into place in the engine compartment and be much less $$$
I am also going to sell a conversion guide that shows step by step how to swap out a DS4 (electronic) IP and put in a DB2 (mechanical) IP and keep your 4L80E transmission.
