Stone, blocks, pinning... Man I have spent a tremendous amount of time and thought on this issue.
I absolutely must have the frame solidly supported. If the blocks shift or slip out that would be bad under thousands of pounds of water and electricity. I could pin the block in place with a piece of sheet metal I guess.
The gravel is cheap though and not especially inconvenient to acquire. That truckfull cost 16 bucks. Haven't worked out how many trucks full I'll need though.
Plus I do really like the vertical support the gravel provides. Ffs I drive on it in the driveway. That's reassuring. Seems solid.
Thinking thinking thinking....
