Interesting Cooling Issue - would love to get thoughts.

I think the slightly higher temps I can deal with by using some of your other suggestions like water wetter. As part of my testing I did pull the thermostat which I'd like to put back in this weekend though.

You have a problem. When one electric fan comes on, the other one should as well. They are wired in parallel to the same contact point, at least in the factory drawings. On my 97 both come on at same time.
If I turn on ignition, but don't crank, and then turn on AC; the electric fans both come on. If AC is off, and I crank truck cold, there is enough air flow from main fan to spin the blades of the electric fans slowly. One day one of them stopped spinning. With power on, I could tap it and get it to spin at a modest rate, but it would soon stop again. Did not blow fuse.
If you replace fans, it is easier to unbolt the tranny "towel bar" cooler (don't un[plumb) to allow fan to slide up and out. Be sure when hooked up that fans suck a paper towel toward grille.
note: why do I preach this "fans suck a paper towel toward grille" ? Because when I got my 97 from the small used car dealer, the fan belt was routed wrong, the fan clutch was blown, and the electric fans had been replaced and wired to run backwards. At idle, with AC on, the main rad fan would just about come to a stop. Finally jafir got me on the path to cool living.

Yes! Thanks again. Just as I began to chill out in it yesterday the passenger window decides to not to go up. Saw your $10 repair post on it so waiting for the outside temp to drop a bit today and gonna head out to the yard to see what's inside the door panel.
Ahh. The life of a Rover owner who decides to make it a daily driver, heck it's the only car I own.
