    Have you tried turning both the gas and electric on at the same time. That's what we do and we only wait about 5 to 10 minutes between showers. Not short showers either
    and neither one of us has complained about running out of hot water.

    That's what we do, also. Gas & electric on when we're showering. And I'm usually second in the shower (within 5-10 minutes of my husband) and I've only had one time that the water just started getting cooler when I was done.

    Thanks for the suggestion, but we have tried that with very little improvement.

    Is your outside shower in the on position ? Often the water mixes there and your hot water disappears.

    Your definition of "quick shower" may be different from others' but I'm writing to affirm what others have said. Our 320MKS with (nominally) 6-gallon water heater (like yours, I believe) was always enough to meet the demands of a wife who likes long, hot showers. Sometimes we showered back-to-back (no, not together unfortunately) and the second person was never chilled out. Plus we usually ran it on electric only.

    Sorry, not what you want to hear, but there may be something wrong. Have you maintained the tank carefully, flushed it out? Here are a couple of videos:

    Good luck.

    I'm thinking there must be something going on with your hot water system. I have yet to run out of hot water while showering with our 6 gallon tank in a 2014 323BHS.

    I hope you find and fix the issue quickly; running out of hot water in the middle of a shower is no fun.

    Cheers,
