I have a 2005 M7 162" with over 4000 miles that I love, but it’s starting to get worn out. It’s time to think about replacing my most favorite sled I’ve ever had. I don't have the money right now to buy new, but I know of a 2007 RMK Dragon 700 155" that the owner is thinking of selling. I know him and the sled, it’s a mint condition, low mileage machine. My question is for anybody who has ridden both, would it be a good sled to replace mine with or would I be wishing I was still riding an M series?
