I may have missed it, but is the truck a necessity for work? If not, I would suggest getting an economy car of some sort for the daily driver. 20mpg is optimistic for most trucks, depending on your driving habits/environment. However, if a truck is required, I would HIGHLY recommend an early 90's Dodge with the diesel/manual. About the best combination you can get for reasonably cheap, and while they're not a Benz, they do hold up pretty nicely...
