Yesterday the boy and I were testing the ability of the P500. We were on a logging trail on the farm and had to get up a fairly steep hill. I was in MT mode at the time I tried to go up the hill but it wasn't able to make it every time I had to shift it would pause and I would lose momentum. I tried this 4 times without success. At this point I backed down the hill and chose AT mode and without fail it went right up the hill. Oh I forgot to mention the trail had 7in of snow. Super impressed with this machine!
