I don't know anything about Nissan, but I bought my 07 DC TRD Taco used back in 07 and so far all I've done is change fluids as scheduled, including anti-freeze and hoses and did belt at the same time. And I had one rear wheel seal go out that I changed. Still on original brake pads. About 166,000 miles and I can't find anything bad to say about it. One wish I have is that they would put a larger gas tank on. In the winter I run mud tires and they do cut mileage down considerably, but that really only bothers me when I take a road trip through multiple states.
I don't use mine to tow, and quite frankly don't think it would do very good if I did. If I put four full grown men and about 10 dead coyotes in the back, it don't take much of a bump to bottom out.
