You seem to be a perfect candidate for the Gorrilla King Kong. I'm nowhere near your size but this stand would handle you with no problem. The best part is the big seat which I believe is abvout 12 X 18 or somewhere in that range. The regular King Kong weighs like 21 lbs. but you can also get it in the Silverback series which is alluminum and weighs I believe 12 lbs. The silverback is around $120 and the regular steel is about $20 cheaper.
