Where does my hot water disappear to?

[Exfireguy]

Coach is a 36' Monaco. Having problems with the lack of hot water in the kitchen and shower. The water in the bath vanity will scald you, while the other taps produce slightly better than lukewarm. The bath is located on the same side of the coach as the heater, while the kitchen and shower or on the opposite. About an increase of distance of 12' or so. Coach is not new and I have never had this issue before this trip. If there was a blockage in the line on that side there should be a drop in pressure or flow-there is not. Any ideas?

Check to see if outside shower valves are on.

You are getting hot water so it has to be a mixing valve somewhere, or you hot line is somehow restricted. I know that doesn't help much but it is where I would start looking.

Is there a by pass valve that may have gotten turned just a bit? If you can look/feel the lines from the hot water tank check the temp by touch... Does the line for the shower and kitchen run off the same line as the washroom basin?. There must be an obstruction otherwise.

X2 on the outside shower valve/valves being open, I'll bet it's in line AFTER the vanity sink and before the kitchen n shower.

The outside shower valves were in the on position, but with the wand shut off, it wasn't known. Once again iRV2 came to my rescue. Thanks to all who replied!!
