I had a 5.4 and I can say there is no way it could even come close to the mpg I get with the 7.3. Not to mention, over 2 times the amount of fuel to haul the same load of quads to the dunes.
And as far as weekly driving.... in the F150 I went through about $40-$50 (back when regular was $2) every two weeks and now I only go through about $25 every two weeks.
Whatever you decide though, you'd better not leave here!!!!!!!!!!
