Seeking recommendation - Blocks for Stabilizer Jacks

I saw wood used in some parks. Ended up going out and bought the stacking egg create blocks from Walmart. (Camping section) I went back and bought a 2nd set. Both have bags to hold them and they weigh nothing at all...or near nothing. I have used them everywhere I go for the stabilizers and the remaining ones I use under the power tongue jack.

They are strong enough for my 190VRB. The plastic is thick and they are durable. You can drive over them for side to side leveling. Now they won't handle a hammer or sledge, but it used properly they are great, efficient, light weight and certainly worth the cost. are strong enough for my 190VRB.
