No damage done luckily.
I was steering and coach owner was remotely operating winch. Flat driver front tire folding off the wheel made decisions far faster than muscling corrective measures and there were no brakes.
Since rear tires were on the ground ramps were aligned with front tires so the truck/trailer could s l o w l y pull away, using coach weight as a ballast easing front end back to earth. Easy, right?
Not this time. Uneven ground caught a ramp and knocked it off.
With one tire on ramp and the other dangling, we now needed a way to lift all that front end weight which was resting on trailer.
Nothing on hand combined provided enough height. Found a junk wheel in the woods full of water that had frozen solid. It weighed about 140 pounds - perfect! Figured in a little geometry, added 4x4s from truck, and ramp for a makeshift wedge in front of passenger tire. Carefully pulling trailer forward enabled upward weight transfer as anticipated. Once that happened, driver side came down opposite ramp. It shifted a tad but it worked nonetheless.
Wasn't hard to pull S&S backwards now. Back to having all 4 on the ground.
2 years since coach ran. Parked with a freshly rebuilt carb and a full tank of gas. At this point the only way it was going on trailer was under it's own power. Wedged marine battery from trailer into Caddy and proceeded to jump/boost with pull truck. After a decent charge and fixing a stuck choke, engine spun over easily. No pop. Then checked and found no spark. After hours in mid-teen temperatures, we were done.
All in all things could have gone considerably worse. Just have to make another trip for retrieval in the near future.
