Got a BCA MTN Pro for my m8000 and my wife's RMK for $150 each at the snowshow and has shovel storage on outside. Found it to be well made and cheaper than than getting the factory add-ons.
Congrats on the new machine! I also bought a 2015 m8000 this year. I changed out those toothpick OEM skis. Got rid of the suitcase can, put a BCA storage bag on, and threw a Pro Armor Tether on. Keep us posted on how that 36" install goes!
