When you can stand up under the truck's rear differential, you KNOW it's stuck! Been there, done that. I was a passenger. Walked a few miles to get the tractor. Freak snow storm rolled in and the offroading turned into a "leave it here and report it stolen" kind of a night, LOL.
Of course we didn't, but it might have been easier. First side airbags I was hit with. Didn't hit anything or an impact, but apparently after a certain degree, they freak out and go off anyways, LOL.
Having tractors, backhoes, dozer, and all kinds of rigging gear on the farm, we have typically been the "last resort" when people are really, really stuck.
Fortunately, most of the time I can handle it all with proper rigging and whatever vehicles are onsite. Usually by the time I get there, they've already called ALL their buddies and there are several 4wd's handy ;)
I've taught a lot of guys about rigging and jacks, and have never charged for any of it. It isn't our business, though, either.
The one time I did drive my backhoe quite a distance to help someone was a rolled dozer over a hillside who was skidding logs. He was lucky to be alive. Nobody else would touch it. I couldn't get close. Had to rig long chains down over the hill and use all rigging and hoe pulling. Never try to go ACROSS a steep hillside, always up and down ;)
Wish I had pics to share ;)
