Review on Vestil SSC 17 Slope Height Length by Dontra Majmudar

I have 2 for my trailer and this thing is huge and heavy. There used to be rubber ones, and they slipped off when we had an earthquake. I've actually seen a large fire truck that used the exact same wheel chocks, so I'm pretty sure it won't let my trailer budge when the next 6.0+ magnitude quake hits.
