I have a regular cab 4.6 4x4 with 3.55 gears and I get avg. of 17-18 but I'm splitting highay and town driving. If I was in town and in alot of stop and go and fairly slow speeds I will get close to what you got or a bit more.

04 scab 4x4 373's average 15.5 around town with 11k.
04 screw with 5.4 and 373 ls city average is 15.5-16.5 highway is 18-19 have gotten it up to over 20. if you do a search on this subject on this forum you will see that there have been numerous threads on this subject with a lot of useful driving tips.
the general consenus seems to be that there is a slight break in period and that these trucks require a slightly different method of driving to get the best mileage
