Water leak

[Woodbine]

Good day
I have a jayco park model 2017 I took a look under the kitchen sink and under the water heater I can see a wet floor at the very back I also looked under the shower in the bathroom and look a little wet back there very hard to get in there to have a good look .When I run my water heater in the morning I see some water on the floor in the bathroom but only on the first initial heat of the day for hot water .After that nothing all day . Any suggestions
Thank you

water travels, just check all the connections from the WH and check the pex fittings.
You also might check under the taps the connections.
