there were two or three times that i got stuck when i drove a flatbed lumber truck,a ford 4500 series or something like that when the impossible would happen,i would get pulled out by a pickup truck. beyoud all odds and they would deliver. this one story is i had to go down a horseshoe driveway that was all red clay. it had rained two days earlier and i knew once i got in there i would not get out. it was about a 6 degree incline with the u at the bottom. this guy had a 2500 dodge diesel. to make this as short a story as possible,i got stuck and he pulled me up the incline while he was idleing!i still had about a 1000 pounds left on the truck. i would not have believed it unless i had seen it. i figgure i weighed in at about 18000 pounds!it made me a believer.
