What do you put under your stabilizers and trailer tongue?

lynx levelers on the side (I don't park on them as intended, just using them as blocks).

wood with a lynx under it for the tongue... my tongue jack lost it's foot somewhere in the Yukon, so its just a piece of pipe now.

I found the lynx somehow avoid sinking into the ground better than a piece of wood, and don't pull out a huge piece of mud when it's time to pull them up.
