Big block with manual transmission recommendations

Most of the guys with big 5th wheels were using Dodge pickups with diesels and manual trans. Everyone else seemed to be using automatics in the Fords and Chevies.

I had a 1986 1 ton chevy with a 454 (7.4 L) but had the turbo 400 auto no over drive. I pulled a 38 ft 14000lb 5th wheel with it. No transmission problems in 15 years.

I currently have a Duramax diesel with the Allison automatic and exhaust brake, I wouldn't tow with anything else. This in my opinion is the best towing setup to come along.
