I had a 97’ 1500 Extended cab with 305 v8 and 5 speed manual.. That thing averaged a bit over 19mpg...I had one like that. Terrible terrible gas mileage. I had to put a chip in it to make it feel as fast as my f150 with a 302.
It rode nice but the gas mileage killed me. I ended up getting rid of it because of the gas mileage and everyone and their brother has that body style truck here.
