Pros and Cons of Tankless water heaters in RV

I notice that some answers mention having no hot water and suddenly having too hot water, having to mix cold water, or needing high flow to turn unit on. All these problem are due to not having the the correct hot water unit or not having it set properly. The correct gpm flow should come on less than half a gallon per minute. The temperature should be set to the temperature desired with no mixing of cold water. That way, the water takes less time to get to the point of use, and does not waste electricity or propane heating water to temperature not needed. That is the purposes of tankless heaters; that you do NOT heat water higher than you need, as well as not keeping water hot when you are not using it. This applies to RV and stick home use.

Your in florida, for home or rv use you only need to heat the water 30-40 degrees to get the temp you want, from an rv tank you may not need even that much, but as temperature range changes increase, the difficulties regulating it do as well.
