This is my first thread. I have a line on a 4bd with 5sp. I do not have a truck yet so I don't know what I want. I will have to be able to carry 6 people. I want a crew but the weight compaired to a f150 ext. cab. I'm looking to get 30mpg on the highway empty. Do you think I can get that with a 4x4 with the right gears. I don't have to have a 4x4 but it would be nice. I also do not know how hard it will be to get a transfer case to hook up to the Isuzu trans. thanks
