When you say more capacity, do you mean to handle your girth? Because I have seen photos here of the snacks you eat. Ha ha!! I am not very petite, one of my nicknames is "The Love Rhino",,, and mine seems to handle my mass quite well, but I have not gone back past 1974. Dunno if it could transport me back to 1970. Might come out looking like a turned inside out Rhino, like in that movie The Fly.
