hmmm so the 7.3 is good for city and towing hmmm
yea low i get about 18 in town with the 7.3 in the city and about the same highway but thats only at about 60mph
so its a decent dd and gets me into a DUALLY
My 01 7.3 gets 18 daily and about 11-13 with a two place behind it doing the damn thang.
My new duramax got 17 freeway on the way home, now averages 14 around town, but only has 500 miles on her. Sure hope it gets better with age.
