My plan would be to bolt the 30 gallon inside with around a 2" gap on the bottom and centered then pour the sand with it on an angle and shake/vibrate it to get good fill. The cooking grate would sit on the 30 gallon's lip since I think they are 18.5" or so diameter and I rarely use the outer inch or two of the grate now anyway.

My guess on benefits is lower fuel burn rate and more stable temps.

Thoughts? Has anyone tried it yet?
Sand is not a good insulator.

If I were doing this I would use a mix of portland cement and vermiculite......I don't remember the exact ratio. I've used this mixture to insulate parts of my pizza oven and the mixture when cured weighs very little. You can use either vermiculite or perlite which can be found in most nurseries, including Home Depot.
....UDS....Mini-WSM....Midi-WSM....Mod-ECB....22.5-OTG....34"wood fired pizza oven....
