I was wondering about those numbers myself. An 8340 lb. tank sitting on 5, 6, or 6 rafters is going to exert a serious load. 10x10 columns mid span and the weight directly over those columns will help. But, 8340 lbs. is a little over the weight of 2 Chevy K5 Blazers sitting over your head....I think some serious thought needs to go into the design of the loft.
