I just got a 2010 800 Assault RMK two weeks ago and took it to Mcbride BC (renshaw). It handles like a dream and pulls like a freight train!! I love this sled and am glad I bought one despite all the bad 2009 reviews.. The only thing I noticed with this sled is that It is not quite as good with high marking in deeper snow. My friends were riding (04 king cat) and (09 Rev) could do some very steep high marking in very deep snow, but my assault would get close to theirs and then sink the back end bad once it got deeper.. Just wondering what anyone else thinks who owns a 2010 assault. Do you have any problems high marking?
