This is for guys who traded in the their perfectly running 2011 or 12 Pro RMKs on 2013 Pros. Knowing what you NOW know would you rather have your old sled back and the extra cash in your pocket or would you rather have your brand spanking new 2013 with not only the sketchy engine and weak tunnel(just like your old sled) but now the possibility of a driveshaft or Quickdrive belt failure? The other option is would you have chosen another sled or brand? Assault, XM or Cat? I am not a worrier, just a complete waste of time. I ordered a 12 drive shaft for a back up. I am going to ride my 13 and go with the odds. LUCKILY I have other stuff to ride if it does fail. This is my last Polaris. They have proven to me that they have systemic problems in their whole company. They are rushing unproven product to the snow and not taking care of their customers when there are problems. I have not had one real problem with my Pro but I feel some kinship with the whole sledding community and hate the way they crap on their customers. Just because it hasn't happened to me YET doesn't make it ok. It is their customer service policy to actively find ways to deny coverage for any reason. Not a company I want to do business with long term.
