The cost of ring gear and pinion sets to regear front and rear differentials to a higher speed (lower numeric ratio) would be quite high, and gearing up too much will make the truck useless for off road escapades. It would take a long time to recoup those costs in fuel savings.
You could get some advantage by installing considerably taller tires during the week while commuting, and switching to the normal all terrain tires and wheels for your adventures.
One caution: Your speedometer will read slower that your actual speed.
Another alternative is to buy a good used Escort or similar car as a commuter, saving the truck for the weekends.

You would probably be looking at $2,500 or more to regear both axles, which you would need to do on a 4x4. I've only seen 3.73's and 4.11's under Ranger 4x4's, if you have 31's you would probably lug your engine running any higher, killing your fuel economy and overstraining the engine.
If you are presently getting 18-20 mpg, as I am with a similar truck, you are doing pretty well for a 4x4.

I haven't heard the term, grade b applied in reference to the roads down here, mine doesn't connect town to town, so it's a low priority when it comes to maintenance, I guess it would be a b road. I'm out in the sticks just the way I like it, but the road does become a mud pit at times, it can get challenging.

You may want to research on how much work is involved to complete this task. I have regeared hundreds of vehicles and i will say, this is not usually a weekend warrior type of job.

Your truck will get optimal fuel economy with 3.73 or 4.10 but if you are currently getting 17, especially if you have an automatic, leave it alone.
