I always run my front legs down about a minute or so before I let them drop freely to the ground just because it seems to give the rig a little more stability. On our last outing I was in a spot that...
I put my legs on about 8" of blocks. I put 2 4x4's facing east and west then put a 4x6 facing north and sounth under each leg. I do this to keep the front legs as short as possible to help with any wiggle. I do that and put load bars angled on either side of the pin to the ground and virtually no wiggle. I just prefer to keep those legs as short as possible.
