new guy from Ohio

[mekanic]

hey there My name is Jim and I am from Ohio and always looking for way to save a dime on fuel.
most of my stuff is considered by many to be heavy users of gas. and they are if you drive without care.
I have a
1999 Jeep wrangler with the 4.0 six I average 18 driving it to work (that is good considering the lift and tires)
1977 ford F150 4x4 with the 400 and a 4speed (tuned carefully I get 16 with an empty bed also considered VERY good for a 400V8)
2008 Hemi Charger with the MDS gets 23 just like the sticker said it would.
and a
1994 F700 with a cummins 5.9L diesel. Havent driven it more than 30 miles yet. I'm hunting for a higher ratio gear set.
here is my big truck:
