You are not reading the right diesel mags if you feel that the content is not aimed at the general population of diesel owners. There are many articles about trans builds for towing and other power mods for the low end meant for towing. I always ask myself first if a mod will help or hurt my towing, as that is the reason I own a diesel. If it won't help me tow, I don't do it. Some of them are tempting :).
Yes I do wonder where where some of the 30 year olds got the money to build some of the superman trucks shown, but hey, to each his own.
