To the Origional Post, that looks like a solid structure with a good footprint. I am a bit worried about the moving shade. im a big fan of the monkey hut and i am strongly concidering getting one of these north poles and putting monkey huts at 90 degree angles for constant shade, with multiple 'rooms'.
ive read a good 90% of this thread, and haven't seen a single mention of either the monkey hut or the puma cave... ?
at a previous BM forum i used to frequent it was the go to structure of choice. it kicked rear in '07, and the puma cave we had was possitioned with the wind, so we didn't really get to test it's integrity.
the nice thing about it.... i can break it down and load it on top of my honda.
here's my photo set of a practice run for assembling the monkey hut:

and here's a 'how-to' site for building:
cost... about $100.
