If so its a gen ll if not its a gen l.
Randy is the warranty / repair person at FR. He is a real good guy and will help out with these type of issues. I personally would contact Gerard and see about updating the WH to a gen lll. They are getting great reviews. I believe they will upgrade it for 300$. You will need to get the new cover painted. Check out some of the posts on the Berkshire page. Our rigs have a lot in common.

Hot water fluctuates

I've had that happen a few times and i think it's air in the lines. I now ensure to run every faucet in the coach both hot and cold for a few minutes and doesn't happen anymore.

My gen 2 model is GSWH-1M.
I run the water pressure with the regulator set a 55psi, if you can get that pressure you can use only the hot water and have a nice warm shower, until the input water temp gets to cold, then I have to slow down the hot water to about half pressure. Not sure if the water will get hot enough when the input temp gets down below 40 degrees.

I have a gen II in my Berk. Adjusting the WH is easy and needs to be changed at about every 10-15 change in ambient temperature. The adjusting knob in the Berk is located in our medicine cabinets. Turn the shower on full hot and let it run until hot water comes out of the shower head. Adjust the knob to the temperature that you want. What you are doing is adjusting the flame height in the heater itself.
Good luck.
