I also have a pair of Mt trail xt gtx and they're terrific boots for the rough stuff.
I've had mine for about 6 months and they seem to be coping with bad weather, bogs, rocks and the usual knocks and scrapes very well indeed. They're very well padded too so they're pretty comfortable out of the box.
Downsides:
Obviously, they're a heavyish and warm boot, so they're not ideal for summer. I've got some TNF adrenaline XCR mid cut approach shoes for this kind of thing.
The inner soles provided are bit hard and thin, for me anyway, so I replaced them with thicker, more comfortable ones.
Also, they're stiff and have a rolling style, so they're not ideal for flatter, gentler walks. Again some approach shoes would be better.
Overall though, as a general, durable, backpacking boot in spring and Autumn over rough hill/mountain terrain they are fine.
