Found a '91 Montero, 4-door with V6 and manual transmission. It looks like what I believe is called a first generation. I know very little about Monteros, but they seem similar in size and cargo capacity to the Isuzu Troopers. What changes were there between the 1st gen and 2 gen? How do these compare to the Isuzu Troopers, both 1st gen and 2nd gen? Is the V6 prone to the same valve train tick that the 3.2 SOHC Isuzu engines can have? How about high oil usage problems? Any serious engine problem areas? How durable are the diffs, transmission, and xfer box? Any problem areas to be aware of?

Thanks!
