D-jap............Haven't you heard anyone call them Durajaps? That is what everyone calls them here
I honestly really liked the truck, but for all the hipe I've seen about the engine it didn't live up to how I expected it to run. It didn't have the low end like I expected, I pulled it down and it wouldn't lug like a trusty inliner. Ran more like a gas engine, sorta like a Powerstroke, but didn't have it under the hood like a 7.3PSD(Haven't drove a 6.0 yet)...........I was told D-max worked the best will the allison, I could understand why after running that one with the 6 spd. Basically, I'd over-rate it if I worked at car and driver........But I think pulling a gooseneck with two tractors would be frowned upon there
