I have an '01 extended cab 4X4 with the 4.7 V8 and auto.
Highway mileage is a shade over 20 when the tach is at or under 2000 RPM. Around town I get 13-15 if I keep my foot out of it. It is pretty quick. I tow a 23. trailer with it. The trailer has a tongue weight of 865 lb. dry. This required me putting a set of airbags on the truck, but there is no lack of power. Off road it does pretty well, but I have yet to really test it in serious conditions. So far (3 years and 50k mi.) I'm pretty pleased with it. The only beef I have is that you can not find a used canopy for it. It is the only truck made (that I'm aware of) with its bed size, unless the new mid-sized Chevy / GMC's are the same.
