And the kicker to this story is:
I did some general measuring earlier this afternoon, and figured that putting the tub at that particular location (on the ground, next to the deck) probably won't work well, due to possible damage to the tree standing closeby (root damage sucks) or damage to whatever slab or pad would be installed in an adequate size to support the tub and give a little "breathing" room around the perimeter.....SO....Most likely it'll be on our deck, after suitable checking, preparations, palm greasing, monkey wrenching, and much heaving and ho-ing. The deck is not going to give enough space to have one of those little wonders (unless I get REALLY creative and put little "tables" up on the outside of the deck to hold 2 of the legs......heyyyyyyyyyyyyy....), so I think I'll have to just "make do" with having a level tub, and skimming the crap out of it as necessary.
But....uh....thank you all SO much for your input.
Carry on.
