I used to wonder if I need my truck... heck, I'm going to grad school in Monterey... why do I need a diesel, crewcab, drw??
Well, it is good for my heart to drive this truck. I wish the heck that urban yuppies didn't drive them as a statement... ruins it for those of us who DO need a diesel for working and makes them too expensive for us to afford, new.
My wife and I own 4 horses... so yeah, I need a diesel for pulling the horses. New trucks are too expensive for us to afford (save for the Dodge, but I can't justify the expense right now--just married about a year ago, already have a new baby and a stepdaughter...)
The 2007 Ford diesels will supposedly have twin turbos and will likely go for $50,000 from what I hear. New trucks are just getting too damned expensive--even for those of us with a college degree and a stable, well-paying job. Not sacrificing my children's college education or my retirement so I can drive a shiny new truck for a few years.
Now, if I had the money... would I go to a gasoline-powered truck? Probably not. I drove a 1991 F-150 (replaced a '98 F-150) for a few years. Pulling 3000 pounds, neither truck had power to accelerate unless I revved the heck out of it. The '98 was a 4.2L V-6. The '91 was a 302. Neither are very powerful engines, true.... but after getting 9 mpg with the '98 and 7mpg with the '91 when pulling a fairly light trailer I knew I needed a diesel. My truck gets 12 at 70 miles an hour pulling 10,000 pounds of horseflesh, trailer, and gear. Gassers have to rev way high to pull (decreases engine life) and get terrible mileage. You'll lose any money you may have saved at 100,000 miles when the engine needs a rebuild. Your diesel would have gone 300,000. Worth the $4,000 difference? Probably not.
The way things are going, it looks like I'll be keeping this truck a long time. Money for paint here, a new Cummins transplant there, and miscellaneous upkeep STILL would be less of a drain on the family than a mandatory $600+/month payment for the next 7 years on a new computer-controlled question mark. That's my kids' education and the downpayment on our 50 acres/house/horses. I don't need ANYTHING badly enough to sacrifice those goals.
Not to mention... I noticed that (at least in the half tons) you can no longer work with pickups as we used to be able to do. My wife's 2000 Silverado and the new F-150 both have front bumpers so low that you can't curb hop without dragging them. My '91 F-150 and my '91 F-350 are REAL TRUCKS, on the other hand.
What incentive do I have to buy new??

They're selling overprice garbage made for city folk who don't work trucks.
Ah, philosophy...
