Have you looked at the backside of water heater.....accessed from inside RV?
On the backside Cold water inlet will be the bottom line going into WH Tank, Hot water outlet will be the top line coming out of WH Tank and the Bypass will be on the line connecting Cold & Hot lines
Valving could be combination of all kinds of valves
3 valve....cold/bypass/hot each have a shutoff valve
2 valve...cold/bypass have valves and hot just a check valve
2 valve...cold/hot have 3-way valves
1 valve...cold have a 3-way valve and hot a check valve
SO access backside of WH Tank and then follow lines/valving to understand which system you have
