Thumbs up

Diesel is more expensive, for now.
I've had a diesel since the early 90s and watched it go back and forth with gas.
The popularity of the big pick ups has it up, as biodiesel becomes cheaper, it will drift back down. Due to similaities to heating oil, it is highest in the late fall.

Convert the truck to a NV4500 manual. There are kits out there to do this. There are NV4500s with GM bellhousings.

It's get better MPG and you'll avoid the heartbreak of slow-revving diesels destroying car-type automatics.

I went through SEVEN automatics with my 6.2. My much stronger 7.3 is on the OEM clutch at 283,000 miles.
Ditto, I have the NV4500 and love it. With 4.10 gears it handles the 41 foot monster in my sig decently. Without the trailer I get over 22MPG hwy, only aero mod is a partial grill block or I can't get it to warm up to the 195 deg thermostat.
If you're not towing heavy (over 8K lbs). A 3.57 (3.51 something like that ?) Rear will help immensely.
That is part of why the diesel Suburbans do so well.

Pray tell why ? Once the factory recall fuel pump was changed to the ceramic pistons, I've had 138K trouble free, abusive miles. Remove the dumb dress cover and you'll never cook your computer (only happens on tweaked motors it seems).
