Check your pump temp after a shower and make sure it's not too hot. Those pumps are designed to run continuously but they do radiate some heat to do so. Might not matter for very short showers.
Just in case you're not familiar with those Shurflo pumps, there are 2 allen screws on the bottom. The pumps typically need to be adjusted, unless you have more-or-less unrestricted flow. In an RV, the goal should be for the pump to run continuously while showering (but it'll kick on and off when you use a sink). If yours shuts on and off while the water is running, turn the screw in the center until it runs smoothly. And if it's smooth but the pump seems to kick on occasionally when water is not flowing (aside from when you first pressurize it), then turn it the other way to reduce the pressure a bit.
FWIW with the pressure set right and using the shower head shut-off, I can do a full shower with <2 gallons of water. Granted I have less hair now than I used to...
