Once he has it, he'll never buy another coach without it. Endless hot water. It will heat your coach also. Maintenance is recommended once a year. I do mine every other year. Maintenance consists of replacing the nozzle assembly, checking the fuel pressure and general clean up. The diesel burner can get dirty. Easiest way to check if it needs maintenance is by smell. If there's smoke or a strong diesel smell while it's running, it needs attention. Most units have an electric switch. While on electric, you won't get anywhere near the recovery time as you do with the diesel burner. I leave my electric on so I have hot water for dishes etc. We turn the diesel on when showering or doing the laundry.....Dennis
