Sounds awful lot like a commercial for the company in question..
Something else you forget to mention in your commercial is tankless water heaters PLUG UP from mineral build up.. That means if you are not on city water (which is highly filtered and softened) you WILL be spending a lot of time CLEANING the tankless heater pipes..
Your city water may be highly filtered and softened but NOT here in AZ.
Water is very hard. So mineral build up IS a big issue.
As for the other aspects of your post.....I agree. Higher BTU, water volume needed for burner, temp control.
Other fact is temp of source water........70*F allows for better temp control than 50*F inlet temp.
Still have big question about RV use/benefit
