I have always thought that the water is very hot because the heater is small, 6 gallons, and to have a descent shower, 6 gallons is not much water. If you mix the hot water with cold, the hot water lasts much longer and gives you a much better shower. Even with both hot and cold mixed, navy showers may be necessary to have multiple showers.
Exactly the reasoning behind the higher temp t-stats.
Look at the Atwood XT Models
Take the SAME 6 gallon tank use a 160*F t-stat with a 'mixing valve' (cold/hot mixed right at tank) so that Hot out is 130*F---then market it as 'equivalent' to a 9 gallon tank
10 gallon XT Model.........'equivalent' to a 16 gallon
HOT water.....then 'end' user mixes cold so that the heated water lasts longer.
Either that OR take up MORE room and install larger/heavier water heaters.
RVs only have so much room to cram all the stuff into.
