Oh yeah, the previous owner of my '98 Chateau with 4.6 and 153k, stock size LTX's, stated he just got 19 mpg at 75+mph on a 900 mile round trip, up from 17mpg on the same trip before he changed the plugs and wires a couple weeks before the last trip. I sorta too the claim with a grain of salt, set the cruise at 63 for 95% of the 240 mile drive home. I was hoping to get 18-19 at those speeds. Was happy to see I actually got 21.85. Around town it's a different story, 16.5 usually, winter 14+ especially if I'm just making shorter trips.

Someday I should try 63 mph, but on the other hand I'd expect that I could be killed by traffic trying to pass me at 20 mph faster than I am traveling.
I have long believed that the 4.6 in an E150 is the best gas mileage drivetrain every put into a full size American van. And I believe the LTX's are the best possible tires for ride and gas mileage--it is amazing that Ford chose such a good tire as OEM on my van.
I travel fairly lightly on my trips and would assume that you are not carrying a big load (maybe 4 passengers and a bit of luggage).
