I recently learned you can't use cinder blocks under your landing gear. Wish I'd taken a picture, but imagine finding a half crushed block under the leg while your wife and toddler are inside and see how fast you run to get your car jack. Could have been messy, we were lucky.
I also learned that one leg will support the whole front of the 5er, but I doubt any good will come from it. Had the crushed cinder block side jacked up and stuck a jack stand under the other side to try to get the other block out from under it. Raised the landing gear and the leg came right off the block without resting on the jackstand.

Does not crush well and would be my choice as well.
Had a friend years ago who jacked up the front of his F250 and supported it with a cinder block while he worked on his brakes. He had his legs under the truck while he worked. He was called inside for a phone call and upon his return he found the truck had crushed the block...counted his blessings that his legs were not under there when it happened.

Be sure the holes of the cinder block are up and down. If you set the block on its side it has no strength. By placing the block correctly you will have to use some wood. Forget the block and use wood to start with.

For the OP -- did you have the cinder block positioned with the holes facing up, sitting on smooth, level ground, with a board laying across the top? It is very rare to have one break, if it is positioned properly. If they did, there would be a million house trailers sittin' on the ground.
I found this out the hard way when I was young and ignorant, trying to block up a house trailer for my cousin. I broke about 6 blocks before I figured out I was stacking them with the holes side-to-side. I turned them over and didn't have any more problems. I thought to myself, "you have a college education and you're dumb as dirt!"

I had the block turned with the holes on the side, did not use wood on top. I'm sure it would probably work the other way with wood, but I'm just not going to use them again. They are too darn heavy, anyway.
