Best potential for mpg?
Has anyone seen a trend for which year seems to net the best mpg with the addition of mods? I'm in the market for a crew cab 4x4 with auto tranny and will do a fair amount of dead heading unloaded. So far I love what I hear about the 7.3L and would like any thoughts on whether any particular year seems to have the best potential or are all 7.3L's pretty much the same?

The only trend is that 4wd and automatics net you the worst mileage.
2wd and 6-speeds get you the best.
After that, it's all about driving style. Keep your RPM's under 2K for best mileage.
As for the mods, an economy tuned chip will give you the biggest results in increased mileage. Also a bed cover will help best on the highway.

All time highest on a road trip (unloaded) 24mpg......Usually 20 to 22 though.
Not bad for a 444cid engine........

My truck gets like 13.5mpg on the highway, and about 13mpg mixed unloaded. Pulling a van trailer I get about 11.5-12mpg.
I don't see how it's possible to almost double my best just because they have a SRW.
I have 3.73 gears as well.

I don't think those numbers are possible with a CC 4x4 PSD
However, it's a matter of how the truck is filled up every time. If you fill up until the gas station pump automatically clicks off, then yes you will get skewed mileage results like this. The pump clicks off because of foam, not fuel, has reached the filler neck. Most folks don't realize that you can still fit another 3-8 gallons of fuel in there. And the ones who do really don't have the time or patience to slowly dribble fuel until it's all the way up to the neck. A 10 minute fillup turns into 30 minutes at the pump.
Now calculate mileage based off that big of a swing, and you can see how suddenly a truck that is actually getting 17-18 mpg on the highway can show well over 20 with hand calculation.
That's why for everyone who tracks mileage religiously, the harpoon mod is your best friend.
