I'm glad I read this thread a while back. The other day I rolled my Toyota going down a hill (dang double shackles - NEVER use them). I did not have my seatbelt on. I was ok, probably because I rolled going a quarter mph, and didn't try to hold onto anything. Luckily I had plenty of tools (all strapped down in the cab and bed). Without any of them and I would still be stuck in the desert cuz there is no way anyone was even going to find us or get to us to pull us out. I used a hi-lift as a come along (w/ two chains) to pull on the far frame rail, while my tow strap looped around the near side frame rail, under the truck, to a tree on the opposite side. This allowed me to pull the truck over onto its side without sliding it toward me on its top. Once on its side, I removed the tow strap and dug holes for the tires to dig into and pivot about as I pulled the truck the rest of the way over. The truck was in reverse and the parking brake was on, so it did not roll downhill when it landed back on its tires. I would have to say that the the entire recovery process was 100 times more dangerous than actually rolling the truck. After cleaning up all broken glass and as much spilt fluids as possible, I remembered something I read on this thread about hydrolock. So I carefully bumped the key (with my fire extinguisher on standby) and sure enough the engine didn't even turn a half revolution before it locked up (the truck was upsidedown or on its side for about 4 hours). I pulled the spark plugs and cranked it over until oil stopped coming out. There was alot of oil in the first two cylinders. I also had to siph some brake fluid into the clutch res., but other than that, all fluids were good. Started right up, and burned oil for a couple minutes, but the dang toyota never ran better. I drove it sixty miles home.
So, I am going to have to say great thread, I'm glad I listened to and heeded the advice on here because it saved me and my truck more damage and money.
Things I learned:
-Double shackles (and any setup that allows your axle to drop without a resisting spring force) are freakin dangerous. Where I rolled, a normal truck wouldn't have even lifted a tire. I still have no idea how it really happened.
-You can never have too many tools-jacks, chains, straps, shovels, axes, saws, fire extingushers, etc. (I needed them all).
-Roll bars are great. I didn't have one, but I had a camper shell which kept the cab from getting totally crushed. I wont ever wheel again without a cage.
-Have lots of water. It was probably 90 degrees and luckily cloudy. A normal southern utah day would have baked us to death.
-Carry all spare fluids, especially oil and brake.
-Be VERY careful when getting it back over. Hi-lift jacks are essential, but also darn scary, especially when tensioning fifty feet of chain.
