I agree with what everyone else is saying. I owned a 89 ford x-cab 4x4 with the old 7.3 disel. I liked it a lot. When I just bougt a new pickup almost a year ago I went with the 97 crew cab 4x4 w/ powerstroke. Night and day difference. I love the power and zip that I now have. I have an 11-1/2' elkhorn camper and it is no problem at all. Like everybody 18mpg empty 13-14 loaded.
