This is not a troll thread, I invite anyone to do the same, use 8th gear and given my truck is one of many this should be repeatable.
I observed that even when going uphill, there are times the mpg gauge is doing over 30mpg.
FYI my speed was between 60 and 70 on this trip.

Ok, I take my words back about trolling. Your first 2 posts had very little info, so had all the signs

.
I have traveled from Philly to NJ coast last summer, so I have an idea of the terrain. It's mostly flat with few hills - at least compared to W.WA.
You owe the forum to fill up the tank, and take a looong trip somewhere

If the 8th gear trick works, you should get 600+ miles on a tank.
