All were 4x4 and 4 or 5 speeds. I have a very hard time believing a 22r can return more than 20mpg at highway speeds in a 4wd pickup. I've never experienced it, even with all syn fluids and a fresh engine.
Now, with both the 3.0 pickup and the 3.4 in my 4runner Ive consistently achieved over 20mpg. My last trip from Missoula Montana to Bozeman (195 miles) at 70mph (slow) I used 7.8 gals there and 8.0 back. Right under 25mpg.
Anyway, I think that's as good as you'll probably get with a 22r. I've never had a 22r leave me walking either though. Even when I put the hood under water without a snorkle, I winched out, let the water out of the intake and she fired right back up.

My truck, 92 Std Cab 4x4 22re 5sp consistently gets 22-24 on the highway and 18-21 mixed. I have stock tires and a Best Top soft top camper shell.
I never run synthetics but I keep on top of the valve specs and oil changes/lubes/gear oil changes.
I just logged 24.1 mpg this weekend going back and forth from Lexington to Louisville.
Driving style has a LOT to do with mpg. I never get over 3500 rpms to shift. Usually I am shifting right before 3000.
