Fuel mileage diesel vs gas

Here is something you might want to consider... When traveling and something happens with the gas rig and it needs a mechanic, I don't worry to much about taking it to some dealer on the road that we don't know. Fixing whatever is wrong is usually no big deal and usually many mechanics are familiar with gas rigs. But with our diesel totally different story. You just can't let "gomer" under your hood of a diesel. One thing might be wrong in fuel system and they start naming what needs to be replaced in ENTIRE fuel system and seeing dollar signs in their eyes.
And I don't care about being the first one on top of the hill. I just want to get up the hill many times. IMO
