That is indeed very nice work, and the rust is very convincing - for a truck far older perhaps. That roll bar is too cool. I always wanted to do an external one on my '92 Rodeo, but the neighbors were already a little irritated with it.
These photos show two different SF Tacomas. They are dirty to be sure, but had no rust on them whatsoever.
Yeah, that bottom photo is the black one again.
Here's another with some guys that Master Box immortalized in 1/35 scale a few years back:
Here's a Hi-Lux with roll bar, but no rust.
For the USSF vehicles, rust like that, even if it did appear would be covered quickly with the closest matching shade of Krylon.

seriously filled out a 2404 since 1986, but there was always "vehicle needs spot touch up." if you couldn't find anything else, just to prove to the commander you were being vigilant.
Final thing, while the roof stowage is clearly evident in one of the Tacoma photos, there were no rails to interfere with the gun, just a platform with square cutouts for ammo cans.. The antennae and other larger items were later moved as well. Some things just had to be learned by experience. (But I'm only stating that on the assumption you'll be adding a gun.)
