This goes for any camper.keeps Jack's from binding and brackets from twisting.Remeber all the cantilver weight of sleeper.Also if you keep one rear jack off the ground ,you will reduce stress and binding of front Jack's.Try it ,the sleeper weight creates deflection thus really requiring only three Jack's to lower or raise camper.That is until leveled and set for use.
