Thanks for the tip on those stakes. Those are a must if one wants a tent not to wind up in a nearby tree due to the sugar sand.
Last year, I saw someone who had a storage tent, but not sure of the manufacturer. It was almost like a canvas Quonset hut, except 20 or so feet long, 10 feet high, and 10 feet wide. This would be useful for not just storage, but providing extra bed space that can be heated (via a Buddy heater on a table) in an event like an ice storm. (It has been an insane winter, and I've barely made it back home several times from a camping trip before the water froze on the roads, so I'm making sure I have the ability to stick it out 3-4 days if need be.)
