We go with the stock Level Up for weekend camping, as the shake is barely noticeable, especially now that we're camping w/o kids! If we're parked somewhere for six or seven days, I'll use a stack of Lynx levellers under each leg in order to to reduce the amount of extension of each leg and this serves to reduce the wiggle.
That said, I only use a couple of Lynx levellers under the front legs (landing gear) as I wouldn't want to have the trailer fall off anything higher than two Lynx levellers when hooking up, and potentially damaging the truck box.
