That doesn't sound correct and I understand your concern. Has it always been like this since you have had this trailer?
One way you might can test for a faulty bypass valve, is to turn the inlet and outlet valves off/closed to the water heater.....while also leaving the bypass valve in the off/closed position.
Now turn on the hot water taps in your RV. Since the water heater is shut off, along with the bypass valve, you shouldn't have pressure to your hot water side. If you do, then I would suspect the bypass valve is letting water thru it.
Just don't forget to open the inlet and outlet valves after your test.
