Got this message via email, and putting it out in public for wider consideration:

I drive a 84 toyota land cruiser diesel "canadain version". New It would gt 28 mpg. They are now a classic and going up in value.
I wonder what would happen if the underside was covered in panels to streamline the air flow? What about the front with it flat grill ?
Lots of pics of the fj60 online take a look see if improvments can be made to reduce drag.

Found a pic, for reference:
I would say "yes" to all the things you mentioned, with the caveat that if you're going to do grille blocking, you'll need a way to monitor coolant temperature (beyond just an idiot light)
Wheel covers and an air dam might be worth investigating too. Have you got a roof rack? I'd also look into a block/coolant heater (3 seasons use is probably justified).
