I have the tankless hot water system in my 2018 Thor Siesta and love it. It will deliver hot water as long as you have propane. I set my water pressure to 55 and have no issues with it. I set my temp to 106 and run the hot water only in the shower. If it feels too hot I SLOWLY turn on cold to adjust it. If you turn on the cold too fast you will get a cold burst of shower water. Once you understand how the system works you will not want to go back to the old 6 gallon tanked water heater system.
