I had looked up the engines and *thought* they were all chain-driven so it looks like that must just be for the newer ones. Any problems with the cam chains/tensioners like they had on the 4.0 SOHC several years ago?

I like the gas mileage of the 4 cylinder engine (if it's a regular cab and regular bed) and it's usually very easy to get to spark plugs and most components but I also have grown to prefer OHC engines on general principles for durability.

Any opinions on which is the better engine, the 3.0 OHV or the 2.3 which I take it is a OHC? Currently I have a Nissan Frontier (got crashed) with the little 4 cyl with about 180K on it and it has had no problems at all. I also have an '88 Mitsubishi Mighty Max with the 4.6 4 cyl with 240K on it. Both have timing chains. The Mighty Max was abandoned on top of a hill for several years with the hood open. The engine (and carb) was froze. I got it unfroze and it still runs pretty good.
