How do you level?

I am a second generation RVer so yes I too have the milk crate assortment of 1xs, 2xs,4xs, and even a set of 5/4" stock. A set of each consists of a short(to go between wheels) and a little longer one for front or back. My last trailer, 26' Layton had very little twist so leveling was easy. My new monster, 314 Jayco w/ slides has proven to be a pain so far. We just took it out for the first time and was not happy with how much it moved around with even my 5 year old walking to the bathroom. I am still searching other threads about leveling and stabilizers with slide outs, and don't want to highjack this topic so I might start a new thread.

Just wanted to also add that I have a method of leveling not mentioned yet.....out here on Long Island we do a lot of beach camping. So I just take a shovel and dig sand out from beneath the high side tires in place!!!!
