The price of regular gas is 3.85 here and diesel is 4.29 and there isnt that great of a difference when you have to fill up. I had an 06 F150 and hated it got 14 mpg driving like an old man...couldnt tow a pea over a speedbump without being in the throttle all the time. I traded my 06 in for my 01 PSD and havent had ANY second thoughts..gas is supposed to be 4.00+ this summer and diesel is supposed to level out at 4.50 tops because of the truckers strikes and such.. think it threw a little longer.. just my .2 cents
