Oh hell, here I opened my mouth (or rather typed another tire name in) and you got another one in the mix!!!

Yeah, I would consider the Trail Grappler an M/T myself. I think Nitto markets it that way because they make the Mud Grappler which I think is beyond a M/T in much the same way the Superswamper Bogger and Mickey Thompson Baja Claw are. The three of them are great off-road, mud and rock tires but not very streetable IMO.
I've got a good friend with a set of Trail Grapplers on his Z71, big hunter who is often off-road. He loves them, but it looks like he's not gonna see 30k out of them, which doesn't bother him much, he had the Nitto Mud Grapplers before these and the pavement wore them to slicks in 18k miles, LOL.

I would consider the Cepek FCII more of a true hybrid between an A/T & M/T tire as I would the SuperSwamper M16s.

My opinion: if your truck is your daily driver or you are basically on pavement more than 80% of the time, stick along the Terra Grappler or ATZ lines with the FCIIs being a more aggressive alternative...

 

Well said Hammer. LOL, you asked for that one didn't you!! lol.

 

Do not disrespect the Duratracs if you live in a snowy area. I've got 315/70/17s on mine in load range D. They are rated for as much weight as the factory E range. These tires are either the best or second (to Swamper TRXUS M/Ts) in the snow of all the rubber I've had on the truck. I've had BFG MTs(fair), TRXUS MTs (great in mud& snow, but wear quick), Cooper STTs (JUNK!!!!!!), D/C F/CIIs (Great on road and in rain, but fills with mud quickly and sucks in snow...did wear well. So far I can tell the Duratracs are quieter than all but the Cepecks, they are better than all but the swampers in the mud, and after putting signs up for the snowmobile club from the truck the other day in the snow, they could be the best snow tire out there. We went from no snow (lower elevations) to about a foot of the stuff. The truck was almost unstoppable. They work great on snowy roads too, not just the woods.

 

Of all the tires you have listed, I'd expect the Duratracs to be among the better tires in the snow.
But to show you how subjective tire opinions are and how people have so many DIFFERENT results and opinions: My cousin who lives in upstate NY has an '08 Ram 1500 4x4. Big hunter and off-road guy and huge trout fisherman. He runs TrXus M/Ts in the summer and takes them off for winter in favor of Firestone Destination A/Ts for snow. He has stated that he has no control on hard packed snow or ice with the swampers.
As far as the Cepeks go, I'll admit they are not in the class of Super Swampers or most other PURE M/Ts in mud, but if you know how to run a vehicle in the mud AND air down allowing the big side biters to contact the mud they do fine. I can't imagine ANY mud being worse than Georgia red clay mud and I get by fine. Granted if I wasn't driving 350 miles on the interstate between Florida and my Georgia farmland I'd have a more aggressive, dedicated M/T, but I need a tire that will still have tread when I get to the back country.
It's also amusing to me that you say the Duratracs are noisier than the FCIIs because my two Jeep buddies who run (and LOVE) their Duratracs make fun of how my tires HOWL... Again, shows you how many different perceptions there are of the same tires.
I know one guy in the 3rd Gen section who has Cooper STTs and raves on them while you call them junk. I'm not disputing you, but simply pointing out how different guys have such different opinions on the same tire.

I still don't understand how you can read one guys review of a tire and he'll bash it saying he wore them bald at 15k miles and would get stuck on wet grass and another reviewer with the SAME tire on the SAME truck will swear he's got 50k on them, still has 80% tread and won first prize in a mud bog last week! But if you read 'em, they vary that much...

 

Very good observations. I have noticed that when people say that a tire is good in the snow, they sometimes make sweeping generalizations. For instance, I had MT Baja MTZ's on a previous truck and that truck would push snow up to the headlights before it got stuck (well, I was actually never able to get it stuck), and the tires were also pretty good on packed snow/ice. However my Toyo Open Country A/T's crushed the MTZ's on icy/packed snowy roads. It is all relative and people don't specify what conditions they are talking about (for the most part), so one needs to draw their own conclusions...

I have decided to go with the Duratrac's and from all that I have read, I'll likely get about 25-30k out of them. I have heard that they are some of the best tires out there in snow, which I drive in for nearly 5 months out of the year. They seem to also be quiet, look agressive and seem to do well in pretty much every condition. I had considered the BFG A/T's but as of late many have said that they are wearing quickly as well and I haven't had the best experiences with them in DEEP snow.

Unfortunately it is $1500/set of 325/60/20's.... UGH

 

That is VERY true. As a rule it's small blocks, small voids and lots of siping for hard packed snowy roads and ice, which is the OPPOSITE of a what a mud tire is. But for deep snow a mud tire does best. So it would be about impossible to have a tire that excels in both...

 

And that is just it right there. Everyone wants a tire that will be a SNOW KING in deep and packed snow, and ice, a MUD KING (which I doubt a large percentage of use even need that aggressive of a tire), and then also want it to be some how silent on the roads at 70mph? You definitely need to pick which more, which is why I lean toward aggressive hybrids between the two. The FCII and the Duratracs are nice too me.

 

Got the 2.5" mopar kit installed today, I also ordered the new tires. I went with the 295/60/20 Nitto Grapplers. There a 34x12R20. I realized the 305 was only 33 inches tall, which is no taller than what I am running now. I certainly could use some more side wall now. Anyways, as you guys can see, the Mopar kit definetely is higher than just level, and seeing I tow, I am desperate for some rake, which will be sublte. I am also adding a 1.5" spacer in the rear, and throwing in the air bags while I'm in there. I am really excited. Btw, the truck drives identical, except the fact I actually feel like I am stepping up into a truck, and driving one. Once the tires are on it will all come together, and when I put on my 20x9 Chromes

 

looks like it sits level to me...kinda hard to tell though since the whole picture looks like its at an angle. Could you get a better pic to post. It does look really good.

 

I can't believe that yours sits so different then mine. It must have something to do with the Crew Cab versus Quad Cab. Maybe we have different rear springs or something. Try getting some better pics and see what it looks like on different angles and terrian. I know if I look at mine on a slope to the rear it look like it sits low but then I move and it is fine. If yours truly sits that high I think in your situation that the Progressive rate coils from top gun might be best for you.
