Changing to 120 deg stat on Attwood is better, but still too hot.
My current suburban is a little better at 130, but still way too hot to suit me.
I realize hot water make the heater go farther, but it is inefficient to heat water real hot, just to turn right around and cool it off w/ cold water.
I solved the whole problem by starting w/ cold heater,... running the heater just long enuff to use hot water only, which ranges from 12 to 15 minutes, depending on ambient temps. This works for me, but not for DW. But us guys always believe in KISS
