I've got a '91 GMC Sonoma with the 4.3/700r4 that consistently gets around 18-20 mpg on my 40 mile round trip to work and back, and that's taking 75 to George Bush to the tollway.
I've gotten 25 mpg out of it on a trip to and from OKC with the cruise control set at about 65-70 and just taking it easy.
The only things that are done to it are K&N air filter and no cats with a single Flowmaster. It's also lowered quite a bit. It has more than enough power to pull a small trailer too.
