There were DEF issues on commercial trucks right from the time it became manditory with 2011 model year trucks and there were still issues when I retired in 2017.

Yeah got hammered again today, unbelievable how much we have. The Bay is covered in deep snow with massive slush underneath, get that long track moving and don't stop!!! A good problem to have lol!

My used, low km sled buying practice's: Be able to do your own maintenance, have a place to do it, have cash, have trailer and ability to travel at any given moment. Keep your current sled.  Find what you want and leave a number to be contacted. Alot of people get tired of trying to sell after one week. Make an offer, ask for a bill of sale for 1/4 of asking.  Most folks will provide something saying "as is where is". More savings for you and most likely already has a trail pass.  I generally ride a different sled every year and always get my money back. When I sell, I still have my backup if I need it.  Or you can always keep it and sell your other sled. There is always a great deal to be had in the used market if your not in a hurry. 

Looking much better now. Facebook page is great. Thanks.

Do what I do buy in April and keep old one as back up. Then you have one two stroke too 👌
