I have Terra Grapplers on my truck now, and they seem pretty good.
The set of Hankook MTs I had on a previous vehicle were OK after I grooved and siped them.
I wasn't at all impressed with the MTRs (similar, but surely not the exact same as the duratracs) that I've had. They look cool, but they're too expensive, too noisy, and have too poor drivability for what they are. I'm willing to deal with a noisy tire that likes to wander if it makes up for it in the mud, but for how well the MTRs worked, I'd have been better off with a set of BFG ATs (looks aside). It's not that they were terrible, it's just that they weren't good enough to deal with their mediocre performance on-road and high price tag. Maybe they've fixed this with the new models.
I like these Terra Grapplers. Seem like a good tire at a really good price (if you look around). When these ones kick the bucket, I'll probably stick with Nitto and try the Trails.
My brother has run the silent armors on his duramax and hated them. They lasted about 20,000km, and that's pretty well all on-road. He's actually ran a lot of those type of highway tires on his last couple diesels and finally settled on BFG ATs for summer and Nokians for winter (not sure which). Seems to be the only setup he can get that'll actually last.
I had a set of Mud Grapplers on my last truck (Super Duty Diesel) and they seemed to last well, but I wouldn't recommend them for, well, anything really. I didn't go mudding, but I got the feeling that they wouldn't be very good in the snow/ice, or in mud, and they were loud as hell on the highway. Look cool though...
