 I bought this truck in early October, 
and have driven it appx 5000 miles, 
and to date, am very pleased with my 
purchase.  I had a 2001 XLT SCab 
(4.6L), and it was a fine truck; 
however, this one is a big step-up in 
ride comfort; the 5.4L - 3V provides 
more noticable power in spite of the 
extra weight (SCrew vs. SCab & 2004 
added design weight).  I owned 2 Z-
28's from '91 to '01, and am used to 
engine power, and this truck has all 
the power I want.  I'm not racing from 
red light to red light anyway.  Since 
2500 miles my gas mileage ranges from 
16.6 to 17.0 mi/gal. - not bad in my 
book.
