dang, hadnt heard about the cam phasers, i knew about the plug issues. the more i learn about the new stuff, the more i want to keep my old iron around! dad got a '05 superduty with a 5.4, looks good on paper, ready for some snow to see how it does with a plow (plow already on) hes pulled his 28' travel trailer with it once and he like how it did. still not sure how it can hold a candle to the '77 we once had. with a 400, 4.10's a C6 and full-time 4wd the only thing stopping it was a long distance between gas stations (9 mpg, no matter what) the '94 with the 351 wasnt bad, but the 3.55 gears kinda kept it from being a awesome plow rig. this '05 seems to be better on fuel, though these days you cant seem to afford to fill it all the way up to check the milage.
