Changing your trailer tires.
Appears our neighbor needed 4 new tires. There's nothing supporting the trailer but the 8 stab jacks. Don't know that I'd be that brave even though I'm sure it will all work out.

Well he has eight so probably okay but they are called "stabilizers" for reason they are not trailer jacks. I sure would not be in it, which I think from your post no one is. I was told not to put the whole weight on them, but I guess that is more if you are using to level. I.e. level with blocks under the tires and use stabilizers to stabilize.
