I am buying a new truck in the next couple weeks. Ford - I 've had several powerstrokes in the past and havn't had any problems. Concerned about the new 6.4 and also heard nothing good about mpg on this engine. Dodge - had a 05 cummins loved it.......any one has any reports of MPG on this with any mileage? On my 05 i didn;t get good mileage until 25,000 miles. Chevy - I like the chevy....but I want a 3500 short box which they don't make in a SRW short box. I have a 37 foot bumper pull trailer with 1000 plus pound hitch weight and concerned if a 2500 could handle as well as the 3500. Any thoughts or opionons would be great.
