I had a set of AT2s on my 2002 Roadtrek and they were good for 60,000 miles. Great in mud and snow. Not noisy, deeper tread depth than the MS2s, and stiffer sidewalls in a Load Range E tire.
The current trend seems to be towards the Agilis CrossClimates. I have no personal experience with them, but may go with them when my OEM Continental tires need replaced. My tires are 215/85R16, and they don't make an AT2 in that size, so the choice is being made for me.
