We can take back to back "modified" navy showers and not run out of HW when both
electric and LP are on. By modified I mean we do shut off the shower head while lathering up but we also give it a little extra time on the rinse off.

My wife and I regularly take back to back showers and we DO NOT use the navy shower method,and there is plenty of hot water to do dishes afterwards. I submit that if you have to navy shower, then there is a problem with the water heater.
Here is what I've learned. A 6 gallon WH, nets 4.5 gallons of hot water, then the remaining starts to become Luke warm. ( this into a bucket to confirm amount. ) so run time is determined by water flow at shower head. For example a 1.7 flow rate should net 8 minute shower. (+|-) I've found just a little hot water at valve then turn cold on. Helps a lot.... This in addition to flow control valve
My WH from cold to hot as mentioned takes about 14:00 minutes.
I worried about running out of hot water on my first couple uses. So I did my usual quick shower as most the time we are dry camping for a week. The last day I did the quick shower, washed all the soap off and then just stayed there with water running. Amazed I got about 5 minutes give or take of hot water before it got cool. That's on propane only.
