I am anxiously awaiting delivery of my new 07 PSD F-350 Dumper. I should have it by wednesday. Just wanting to know if there is anything you all would recomend in the PSD maintenance department. I'm pretty familiar with vehicle mechanics, but I have never owned a diesel before and would like to get a heads up on anything that you think I should need to know. It is a six speed manual 4x4. I plan to plow snow with it this winter (Boss 9'2" V plow), haul a bobcat around with a hoe attachment, general landscaping, etc. When I test drove it I noticed 2 things that bothered me just a little. 1. It has not low end grunt, but kicks in pretty good in the upper rpms. 2. The tranny is pretty tricky to shift at first (possibly because it is new?), seems like the gears are tight to get into. I've heard that diesel's are hard starting in the cold. Will my truck have a oil pan heater to plug in when it gets real cold? Is it necessary, if so - at what temps? I've also heard that it is better to leave the engines running rather than off / on, off/on, off/on (like snow plowing all night). Finally, what fuel mpg can I expect? I also have an F-250 Triton V8, I can't imagine the mpg is any worse than that. Thanks in advance!
