tk,
When you're at it, and since the truck has some miles (I have a '99 with just under 85K) take time as others have suggested and really get to know it.
Since you're already there, I would remove the metal "skid plate" that sits under the engine as well. Blow out and remove/flush out sand and mud that might have been accumulated over the years. Do the same with along/on top of frame members, the tray that protects the fuel tank, etc. (lots of dried mud caked in there if car has been off-raod and not cleaned out).
With skidplate out of the way, you can easier inspect coolant lines, a/c lines, take a peak at the power steering, etc. Check rubber boots and CV boots that there are no cracks/tears.
In most places here in the U.S. it might not matter, but where I'm originally from (Sweden), having cavities (like the LC does have) underneath that can accumulate mud/sand/salt and hence retain moisture, will only lead to significant rust issues down the road.
I bought the LC not only because it was a "Dream Car" at the time, but also because it is a relatively easy car to work at. On my 300ZX, you could not even fit a regular shop jack underneath, here I can easily slide in w/o even lifting the car, or drive it up on ramps. Such ease of access

But, I still miss my 300ZX... :-(
