Since you've run out of hot water so quickly, it may be due to having the winterizing valves turned the wrong way. That causes the cold water to enter the top of the tank and almost immediately mix with or replace the hot water. So, check your valves.
Second, most experienced RV'ers take "Navy showers", where they turn on the water, get wet, turn off the water, soap up, then rinse off. This reduces the amount of water used considerably.
I think I have them right. There's no arrows saying off or on. So I have to guess.
And we take navy showers. I've been rving my whole life so I know that's just part of camping.
