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

They work as is only with thick steps. I used them to align but when they were added I was too far apart from the others. Boards work the same way, but take up more space than they do and weigh a lot more. They make excellent jack pads because they keep the strut legs dry. With a 2 axle trailer you need two packs to get up a row and then you need good chocks to keep the trailer from rolling off. I switched to Anderson. Aligners instead for alignment unless something is more than 3 inches from alignment. I still have them just in case and now use them for jack stands. Anderson levelers are more expensive but can do about a foot and a half when moving a trailer up to 3 inches compared to what some of them take back and forth. The Andersons also have a last as part of the solution and want to sell you another part for less flexibility.
