Gas VS Diesel F250

I don't get it. All the gas guys say how cheap it is to maintain and repair the gas motor. All the dealers are charging close to $100 per hour labor rate. I have owned diesels for over 25 years and could count on one hand the times any of them were in the Ford repair shop. I keep all the filters and fluids changed regularly. That must do the trick !! I hear from people all the time how it cost an arm and a leg to get their car/truck repaired. If you own a diesel and it has motor problems or if you own a gas motor and it has motor problem and goes back to a dealer it is going to cost big bucks !! They don't work on gassers any cheaper than they do diesels. That excuse is getting kind of old. There is a...right tool for every job... why do you think all the Construction Co, Utility Co, Gas and Oil Service Co , etc. etc. all run diesel trucks ? Sure they have gas trucks too but they are for just carrying people and small items around. I don't care what anyone decides to own...but there is a....right tool for the job.
