Also, did you hit the booster button before starting your shower?

Increasing the temperature at the mixing valve will limit the addition of cold water to your hot water tap.  So, if you have a hotter temperature coming from the limited 2.5 gallon hot water tank, you can prolong your hot shower by limiting the output of the hot water tap and adding more cold water.  Also, what Jenn said.  Navy shower.  Use the boost feature.  As Rolling BnB notes below, the Alde hot water tank temperature increases for 30 minutes (cabin heat delayed during this time).  We boost it a half hour before we shower then again at the time of our shower.  Starting with hotter water lets you use less hot water as you add in more cold water.

@GATabber The booster setting raises the water temp in the tank so you would use less hot and more cold to balance the temp. Should make the water last longer.

So far, we've only camped at Virginia state campgrounds that have not only full hookups but bathhouses with hot showers & toilets.  So, we've never used our shower, but then we're not even at the one year mark either.  We have yet to put anything but liquids in our toilet either, but really appreciate having it at 3 or 4am.
I think we will eventually use our shower, and when we do, it will be wet down, water off, soap up & rinse off, not the 5+ minute continuous shower like at home.
