Hot and Cold Hot Water
I'm sure anyone with a Suburban gas/electric 6 gal water heater (and other heaters too) have experienced two separate problems - the unmixec hot water comes out blazing hot, and when the water-saver s...

Suburban uses 2 sets of thermostats for electric (120V AC) and for propane (12V DC) that are preset for 130*F & 170*F
There is an optional 120*F/170*F set for electric only.
OR optional 140*F/170*F sets for electric and propane.
One of the pitfalls of RV water heaters.........how to get adequate gallon capacity and be small enough.
Higher temp set t-stats accomplish that..........but turn on just hot water handle and you get water hot enough to scald. Hot/Cold need to be used at faucet.
Water heaters with 'mixing valves' allow even higher temp t-stats and then mix hot/cold to deliver 130*F water on hot system....still hot enough to scald.
More usable hot water but user still has to mix hot/cold at faucet.
Also higher temps inside WH tank help prevent/control bacteria growth
Shower......
When you turn off using shutoff on handle the hot/cold mix in faucet.
When you turn it back on you either get blast of very hot or straight cold.
Turning it towards wall prior to turning back on is one solution.
Adjustable aftermarket mixing valves can be installed on any water heater.
Just a matter of some fittings, valves, piping.
They can be adjusted (OEM are 'locked preset'----can be 'unlocked' and made adjustable) so higher temps can be used for water in tank and then control output temp so it isn't dangerous.
