I would bet that if you put a hose and valve on the water heater drain, the same thing could be accomplished.
But that would involve him having to go outside to run the water. He doesn't want to do that. His current setup lets him run the water from the kitchen faucet.
Not if the valve is turned to a position where it isn't full flow. I envisioned opening the valve, initially, to full flow to add a lot of hot water and then necking it down to a mere trickle. The downside is that the pump would occasionally run because of the small amount of heated water displaced but this would be "hands off" if set up correctly. Full manual operation could be done with an electrically operated valve.
This would be a connection to the water heater drain, not to the pressure relief valve.
If I was doing this type of system, I'd just tap into the RV's plumbing lines and forget about any exterior hoses or connecting to the kitchen sink. There's lots of ways to skin this cat.
