I used one of these between the hot water pipe and the hot faucet, and then I added one of these at the base of the shower head hose. No more icy or scalding water when taking a Navy shower in the TT. Pretty easy install.

another possible cause of the cold water problem is WH bypass systems with ONE lever, rather than the TWO lever systems. The one lever systems use a one way check valve that often has highly non linear characteristics. The result is very noticeable water temp changes with flow, very noticeable when water is down to a trickle then back up again. Solution, pull the check valve that is installed and install a WH bypass with two levers. That solved our issue along with two other camper friends complaining about the same problem.

I tried most of the “All you have to do is just.........” suggestions given here, with very little improvement. I say “most” because when you dry camp as often as we do, and only have a 30 gallon fresh water tank, dribbling the water works against our need to stretch every resource needed to extend our stay.
What finally fixed it for me was a Thermostatic Shower Mixer Valve.

Are you having a problem with the cold water blast in the shower or does the one way valve just seem like a good idea.
Many RV water heaters already have a check valve at the exit line, it's possible yours already has this.
Does your RV shower head should continue to dribble water out of it even when you flip the switch off..

Per the video when you use the switch on the showerhead to shut off flow, the cold water will back fill into the hot water side since the pressure is greater and thats why when you turn it back on it will be cold for a few seconds.
Since both the hot and cold water are pressurized by the self same PUMP that.. it male bovine produced organic fertilizer (AKA BS)
What happens is when the water stops the hot cools a bit and "Contracts" sucking cold in. The solution is to use a better valve that does not 100% turn off flow. the Oxygenics "Smart Pulse" valve is like this. it allows a dribble of watter to flow. So does the generic valve I got at Mennards years back (Alas no link it's been 15 years)
Either of these solves the issue for about 10 bucks.
