If i were you I would not be afraid of the electronic diesels. They are very good trucks. we have a couple of 91 Ford F450 Super Duties that are about to turn 200K and they are used in an electric utility and run nearly 24/7. Transmissions can be a pain after about 150K but if you are not pulling a load continously then you may not have problems.

The dodge with cummins diesel is a great engine, just get a standard trans as the dodge auto is crap. My dad had an late eighties or early 90's and he got 100K on the trans and clutch before problems and he pulls a 37 foot fifth wheel travel trailer 9 months out of the year. I really think he got screwed on the trans he brought it back with him and the only thing I could find was a worn out shifter cover.

Hope this helps.............and good luck.
