I doubt it's the wh with the trailer being just 6 months old, I would get on the roof, remove the vent cap on the sewer vent and measure down to the bottom of the tank and then hook the vent pipe itself and see what the difference is. It should be at least 3" or 4" difference. See if you can determine just how deep the tank itself is. The vent pipe should not stick down much over 1" into the tank.
