I thought about the winch system, but my plane weighs around 5,000lbs.
Pulling on the tail tie down ring might just rip it off. There unfortunately
is no way even four people could push it upslope on our ramp on the ice.

I use a 10HP tug that goes under the nose wheel, and is big enough for a
King Air. I'm going to stop at our local Farm and Fleet
(hardware/construction type store) to see if they even sell chains. I will
also look at a long runner type carpet to place under the tug, which may
help the traction.

It's still all a pain.
