Decisions....Gas or Diesel

I am a "new" first time Cummins owner. I had a gas 3/4T, the old "white whale III" but it was a short cab and needed "something" IE a 5 speed instead of torqueflite, to tow better. I would have fixed it up, but "small cab." I found an 01 Cummins, big cab, and "I thought" I wanted a 2WD. I wish I'd bought a 4wd. It's a 5 speed, I did NOT want an auto. Unfortunately, it does not have a limited slip rear axle.

Other than wishing I'd gotten a 4x4 after all, I'm happy. I don't use it that much, and THERE IS ONE IMPORTANT consideration. That is 'short trips'. There's lots of stuff I do here, that is a couple miles, maybe 5. Even grocery shopping is only about a 10 mile trip, but of course I'm at the store long enough it cools off some. So properly getting it warmed up is an issue for "errands."
