This is what I put in my sled trailer. Made for the cold and has the transfer switch built in. Looked at several dealers in AB but ended up ordering from these people out east for much less.. It will also charge your batteries when plugged in...
Just be aware that if you do the mod and have a battery, this will drain your battery if it sits for a long time. Did it on a XP & XM - works well. Also needs to have new keys programmed at the dealer.
There has been some trouble out there of late. People destroying the owners equipment etc. Heard that someone even threatened the owner with a knife when he told them to get out of his gravel pits. These are private and still active gravel pits, but there are other places to ride around that...
