I prefer using solid concrete block or the “termite” block over a regular 2 or 3 cell, just an extra safety factor. Years ago I got my hands on two chunks of cut sandstone and I’ll set my 6 ton stands on top of those.
I have put all four corners up on stands a few times. I don’t like doing it, especially if you’re not on a solid surface, it’s just begging for disaster to strike no matter how you do it. I had something like 7-9 jackstands under my green Ranger plus 4 or 5 jacks when it went down. I was going for a tire to start putting them back on when it happened. Mind you, I put crushed limestone down and set jackstands that are critical on something over the leveled limestone. Ground was really wet and soggy, one second it was stable and the next second it was on the ground with a jackstand through the gas tank…
Much better to work on one end at a time. Or, like is going to happen with my lowered green Ranger in the near future where I have to pull the entire front axle out to fix a frame crack… I’m going to drive the back up on something solid and then put my sandstone blocks and 6 ton stands in the front on the frame. That way I have some height under the truck but the back is still sitting on the tires.
