Review on 🟨 Camco Durable Leveling Block Caps - Create Even Surfaces & Maintain Stack Height, 4 Pack (44500), Yellow by Cory Jacobson

I use these blocks under a jack with tongue and wheels on our 33ft ultralight travel trailer and they are GOOD ( like for stacking) and the case in which the blocks are stored), but they are not very durable. They can be an advantage if you always park your house on the sidewalk, but blocks will crack and split if used on gravel (1-1/2" to 2"). They wouldn't break if you used the board under (and in the case of a tongue and groove bushing) under the blocks, but the main reason to BUY these blocks is to avoid having to carry around a bunch of wood to pack them straighten. Camper! That being said, even though some of our blocks have been hacked, they still seem usable, so we'll see what happens in the long term (>1 year).
