Opinions needed on Tow truck - Diesel or Gas?

Glenn:

As I mentioned above, I've been in your shoes. We had a '91 Chevrolet 3500 crew cab with a 454/auto/4.10. At that time we had a 44ft gooseneck that weighed 9K pounds empty. After we munched the 4L80E a couple of times, we upgraded to a special heavy duty 4-speed manual with a gear splitter attached that Moparts had in his shop. This helped a lot, but I wanted more so on went a Paxton and a full dual exhaust running through headers. While it ran like a scalded ape, it necessitated a 110gal. auxillary tank in the bed of the truck in addition to the dual 20gal. saddle tanks. MAJOR gas hog. We then upgraded to our crew cab TopKick with the 3116 CAT diesel and haven't looked back. I will NEVER go back to a gas rig to tow with.
