This is a LS ext. cab 2WD oilfield truck, w/4.8L V8 engine, driving mostly highway miles. I get between 15-18mpg, and have a hard fiberglass tonneau cover over the bed. I would not tow anything of weight with this truck.
Its very comfortable, according to others who have ridden in the oilfield standard F150's. However, when A/C is on it seems hard to adjust to the correct temperature, always "too hot" or "too cold".
RR P235/75R16 Goodyear Wrangler tire blowout at 40,000mi, (15,000mi tread left). I have replaced with a set of Bridgestone P245/75R16 Dueller AT Revo. The aggressive tread pattern and wet weather compound makes these tires handle like a dream in the oilfield.
Having only regularly scheduled maintenance from GM dealership, there have been no major problems. I have complained about Allison trans; shifts hard, slips every once-and-awhile in first. They could find nothing wrong with it. I got the trans service, (50K), and this tightened up the trans for awhile. Now its loosey-goosey again. However, with the abuse it takes, I feel it will last until 140K when I get another truck.
Windshield seems rather thin. It has 3 star chips in it. However, they haven't spread at all like the F150's winshields do.
Oilfield standard is this: F150 is the overall best truck. Good price, excellent reliability. However gas mileage suffers compared to Chevrolet. Our company let us pick Chevy or Ford, because of similar pricing. Even though Ford will win out in reliability, I chose Chevy since it has sex appeal. Gas mileage is also better, (I have a Chevy personal truck). Dodge is also a nice truck, but I hear of auto trans/suspension/body problems in the oilfield.
