I have been in that spot next to the fence myself, no fun...Once I got out of my ditch, My modern Jeep pulled the 2002 Suburban out with minimal effort. Fortunately, the Suburban wasn't near as stuck as the Jeep.
The Suburban slid off just enough that it was sending power to the tires off the road.
The Jeep was a different story. Three foot deep ditch with an old steel farmer's fence directly against the driver's side. I almost had it out unassisted. I backed up into a tree that was just on the other side of the fence and used it to pivot my front end onto the road. Unfortunately, the fence hooked my bumper and swung me further into the ditch.
