Taking the toy hauler up to the ski resort? Any problems?

Thanks for the chain and road suggestions. I figured I would go over Tombstone heading up to HooDoo but head back down 22 to the lower hills that are free of snow to get home. Might take an extra 1/2 hour but well worth it. So do you put the chains on before you hit the snow going up or give it a wait and see method? I figured I would use trip check to see what it looked like on the ODOT cameras and if is snow packed put the chains on ahead of time just before the snow or right when it starts.
