Thanks Clancy! These are both new this last year, and I am finally getting to use them now.
The Ranger works well as long as the powder isn't too deep. I had it in a couple feet of sugar snow last week, and it got through it pretty well. I had to back up and push forward on some slopes, but it kept going. I think that was about it's limit for powder though.
The RMK 600 is a HUGE step up from the 500 Wide Traks we have been running. We still have some Wide Traks, but I will slowly phase them out for the RMK's as I can. They are not as comfortable on the hard packed trail, but they are so much better anywhere else.
