Review on 🔧 Camco 44510 Heavy Duty Leveling Blocks for Single and Dual Wheels, Hydraulic Jacks, Tongue Jacks, and Tandem Axles – 10 Pack (Frustration-Free Packaging) by Marc Farrell

Made of plastic and inexpensive, so these facts tempered my expectations (hence the four star rating). Here are two things prospective buyers should know: 1. Ten blocks (the number included in this package) is not enough to make a "ramp" for a stack of three blocks (if your alignment requirements are that extreme) for dual axis provide mobile homes. 2 . They won't be sitting on the pavement - the tires will pin them to the pavement if you don't hold them. The first time I used them was on the sidewalk and was thinking about sending them back. until I used them on gravel. In the gravel they seem to have enough "bite" to keep the blocks from slipping. Still, they're stackable, they're lightweight, and seem to carry quite a bit of weight.
