I was thinking of going with either concrete pier blocks, one in each corner and then two on the sides on top of a couple feet of gravel or 2 4x4 PT skids, sitting on top of the ground. I like the weight displacement of the skids better but prefer the longer life of the concrete over PT wood sitting on the ground. Other pros and cons of each? Also I live in a really cold climate -30C, is one better than the other for shifting frost levels? thanks

my dad has a 16x 20 shed at his RV campground .. he was able to get some railroad ties to keep his off the ground..He has had the shed there for about 20 years and the railroad ties are still in great shape with no shifting just a little bit of sinking but they all are sunken about the same amount so it is still nice and level. he put them in a square around all the sides and then put 2 along the the 16ft section 8 feet apart and 4 along the 20 foot section 5 feet apart.

RR ties are great, but awkward to re-level if needed; that may or may not be an issue, and I suspect not. Concrete piers w/ an adjustable bolt in them are easier to re-level. Set your beams in them, build and go.

can I just float this with concrete piers our should I bury sonotubes below the frostline, then attach the piers to the concrete with adhesive? Would a small shed like this shift much if I were to float it?

The only reason I ever worry about a building floating around is if it has plumbing pipes attached. A shed can bounce around all it wants to and you'll never even notice it, I suspect. I have never heard of anyone locking a shed to the earth.
