I carry the orange plastic blocks along with pieces of 2x8 that are cut at a 45 degree angle to make it easier for the tires to ride up on. I mostly use the plastic blocks except where you encounter soft soil conditions then the wood is better because the open web of the plastic blocks sinks into the sand. I have everything fit into the plastic crates for ease of storage. I also use a level on the floor then raise the level so the bubble is in the middle and multiply the height difference that tells me how much I have to raise the MH.
