+1 on keeping it at 130 so you have more usable hot water. 6 gallons is barely enough even with Navy showers.
The risk of scalding goes up a lot at 140 degrees so I don't recommend going there (not that the OP will). I just installed a new WH in my home a few weeks ago and it has a digital interface where I can set the temperature with a few button pushes, up to 160 I believe. It defaulted to 120 and I set it for 130.
Just below 120 you start flirting with Legionnaire's which is partly why I prefer 130.
