When I bought my PUP I got some cheap rubber chocks from Harbor Freight. They worked well enough but my birthday present to myself this year was a BAL wheel chock that I will be trying out. I heard too may good things about it, and the regular chocks do take up a lot of space compared to the BAL. I use the BAL leveler. I thought about the Anderson but I do a lot of camping solo or with my son and the Anderson is much more of a two person one than the BAL. I like being able to drop the trailer and slide the BAL in and fine tune it. I can also tweak the height a little to assist in directing the AC runoff to the street side of the trailer. Biggest drawback is the BAL takes up a lot of room, but overall that is a trade off I am willing to live with considering the benefit.
