You might check you winter storage valves.
Yes, check the winterization/bypass valves. My coach has 3 next to the water heater and if they are set in the wrong configuration, the same thing will happen to me.

if none of the things suggested by the other posters helps I would carefully get some hot water directly from the heater relief valve and check the temperature, It should be about 140 degrees unless you have a tempering valve then it should be about 160 degrees.
It the temp is right you have a cross feed between the hot and cold water somewhere.

Be aware that many water heaters also have a CHECK VALVE to prevent mixing of hot/cold due to slight pressure difference in the two sides of the system. They can go bad, particularly if the coach is used in an area with high mineral content in the water.
