I have had my XV-3 with the deluxe pull out galley for about three years. In that time, the Camp Chef 5 liter Trident water heater has sprung leaks three times. The first two times, the problem was a loose fitting inside the water heater. The first time, I left the water heater in place, took the cover off and had very little room to work with, but I was able to get an open end wrench on the fitting and tightened it enough to stop the leak. That lasted a few months, then it began to leak again. The second time, I took the water heater completely off. In order to do so, I had to take the cover off the galley box in order to get access to the water heater mounting bolts and to disconnect the water lines. With the water heater on my workbench, I had more room to work, I tightened the fitting and reinstalled the water heater. That lasted over a year and then the mounting brackets broke, so I purchased a new Camp Chef Trident water heater. Before I installed it, I removed the cover and tightened the fitting (it was loose). Recently, the water heater began to leak again. I again removed it and discovered that this time, the leak was due to a crack in the heat exchanger. Unfortunately, Camp Chef's web site shows that the 5 liter Trident water heater is out of stock. For the time being, I have bypassed the water heater connection by using a 1/2" pipe nipple between the cold water inlet (the blue PEX line) and the hot water outlet (the red PEX line).
