I am thinking of either of the two, however I am not sure which would be better.
While a ATV will have the power to pull out my fish house. It does not stay on top of the snow like a snowmobile, On the other hand a snowmobile will have the ability to stay on top it will not be able to pull my 8X20 fishhouse.
I could put in $1500 – $2500 into a sled or just put that money toward the tracks.
From my understanding Millacs is hard to get around right now and I suspect it only to get worst. 
Okay thoughts?
