[7T2]

No lesson learned the hard way, thankfully. Sorry, no gory pics.

I usually use them in pairs as well, but I always thought I was playing it safe because I always thought a single jackstand was good for well over the total load I was supporting. Turns out this is not the case.

case in point: Recently did the brakes on the front of a C70. Total weight is 27000 pounds. I figured I had plenty of capacity by using a pair of 6 ton jackstands to support the front axle. (6 ton = 12000 lbs x 2 = 24000. Should be fine for just the front.) In reality the jackstands were good for 12000 lbs TOTAL, and while there is probably less weight on the front axle than the rear I was probably pushing the limit doing what I was doing. I'm in the habit of leaving the jack in place as well, so I had a 12 ton bottle jack there for backup, but it's nice to have some margin of safety instead of pushing the limit. I now have a set of 12 ton jackstands that should be OK for one axle of that truck.
