OK, OK - I'm DE-Moted back to Private. Sure - you can't use the winch either! How silly I am. I was having dinner, thinking about the problem and started to choke up when I realized the "slight" problem using the winch. All together my oversight!
Tom - Guess the winch is a mute point just now. Best place to practice with it is at home - try it first there. Do some reading on it first.
Do you have trees? Something to dead man to. You don't have to lift the truck - just take the load off it. I have a 5 ton come-along that would probably do it, or something like it. Even a pick up winch, using trees, with several parts in your line. Use a snatch block to double or triple your pull. Or, tie it off, as tight as you can, to trees. That would make it safe to get under it, on the uphill side, to jack it up. Assuming you have a good enough surface to support a jack. Using two jacks would be best. Take a bunch of blocks. Be best if you could get it before it snows.
Good Luck. Sorry about my Oversight?
