There aren't any advertised brands...
Even Scott's insitutional brand isn't advertised. In supermarkets "quick dissolve" TP is likely to be the bargain house brand. Just go by the price...if it costs a fraction of the premium brands, it's prob'ly what you want.
I hope you pump your tank out once a week, Ross...'cuz a dozen sheets of Cottonelle at a time left to accumulate in the tank is gonna block your tank discharge sooner or later. Just for fun, put a sheet of it in a mason jar full of water and leave it there till it dissolves...as long as it takes.
