Thanks to all for your replies. The concern with fuel economy is not cost, but range. Trying to gain some confidence that a new gas 3/4 ton (probably Ford or GM) and leaning toward a Silverado w/ 6.6L and 3.73 rear end will go farther on a 34 gallon (or so) tank than the current truck takes me on a 25 gallon tank.
if your worried about range, go with the diesel. better MPG directly relates to more range. empty the gassers might get decent milage but loaded up they fall far short of the diesel
