We have a
Casita and the Andersen (There are other brands of the same device on the Market: The Blalock is aluminum) worked well enough. But we now have a Big Foot Tandem
axle, with the
tires placed fairly close together. I don't think it will work as a leveler. We will be using wood blocks and Lynx levelers.
The Andersen did not work that well for us in sand of the SW desert region or in mud. It did kick up into the wheel well a couple of times. My
Casita has the OEM high rise
axle and it was raised an additional 3" higher by Little House Customs, so I have plenty of space in the wheel well. It still had me worried and almost, but not quite, became stuck. Also it slips when wet, both the wheel on the leveler and the leveler on wet grass when pulling up on it. So we carried wood and lynx blocks in addition to the Andersen.
The BAL 28050
Light Trailer Tire Leveler, is very good but a bit heavy and it would be nice to have an electric drill to help out. I used a ratchet which worked well. The Bal is really made for a 14" tire. Mine are 15", so I would drive up on a 1" or 2" block of wood then the Bal would slide under the 15" tire very nicely.
