Hello, looking at a left over 2014 SnoPro 162 for a pretty good price but reluctant to pull the trigger yet. Question 1, what needs to be done right out of the crate or is it truly a box stock rideable? Question 2, is the evo stage 2 the way to go or will it expose the next weakest link and put me into endless upgrades until I have it "right"? Question 3, stock skis seem like they are not the ski for that sled so what is the general idea on a good ski for the sled? Question 4, belts, are these still belt blowers and will I be shelling a 160 dollar belts every 100 miles? Thanks for your help/opinions!
