Sounds like something I guy I know did. A couple of weeks ago at the Silver Lake sand dunes his throttle stuck at the top of a hill. He caught some air and when it touched down the LH knuckle broke in three pieces. Tire flopped in or out and then the winch dug in and flipped it over on the top, on the side of a very steep dune. Luckily they had a roll cage in the rear, nothing fancy but it held.
Some people helped flip it up on its side so they could get to the last kid in the rear seat to unbuckle him, while the truck was on fire I was told. They surpressed the fire as best as possible with the one fire extinguisher they had and kept throwing sand on it for about 20 minutes keeping it contained. DNR showed up and guess what? They don't have fire extinguishers in their trucks! Well it finially got out of control and when the 38.5s on the high side caught fire they rained liquid burning rubber on everything.
The remains are sitting in the yard on a trailer. This is by far the worst burn I've seen due to the position it was in. The body was left at the junk yard up their, trans case is melted all suspension bushings gone, all tires gone. Hopefully most of the motor will be salvageable, one side might have got hot enough to damage the aluminum roller rockers. Motor was only 3yrs old, GM crate L31 with HOT cam kit, weeks old 5.13s in the 3/4tons, year old 38.5 Baja Claws.
When I get back from being out this weekend I'll try to remember to post some pics. Now he is looking for another rust free blazer. My project for now is to salvage what I can, which ain't much
