If your tank isn't already full, the water pump is on, your batteries aren't dead, and your bypass is turned off, there's no reason at all that your pump shouldn't be running to fill that tank. I'm not sure about your trailer, but in mine, the pump is really, really quiet until all the air is pumped out of the lines. If you haven't tried yet, you could try running it with a hot water faucet open. That way, you'll know if any water at all is going into the tank. If water comes out, but it hasn't filled the tank, a bypass is still on.
Not sure what kind of bypass you have - on mine, it's a single valve that I have to switch, but some have more than one valve that needs to be switched.
Hope that helps - if your pump works for everything else, there's no reason it shouldn't pump into your hot water tank.
