I have 224,000 miles on mine and it runs as good as the day I bought it. Cummins makes a fine engine!
Ford has hired Rouche(sp?) engineering to make a liquid feed propane burning version of the 5.4L triton engine for the 2007 F150's. They should haave the first working prototype out next month. Since I have 1500 gallons of propane storage here and I get it for less than half of what diesel costs, I will certainly take a hard look at these when they come out. When I bought my diesel truck, I could fill it up for under $40! It's over three times that now! And to make it worse..... It would seem that every single thing I buy has gone right up along with the cost of fuel. Really cuts into the profit margin of running a business.
