Hot Water Replacement

I need to replace my 20 year old water heater in my Fifth Wheel. I am wondering if the On-Demand heaters are a good choice? I currently have a suburban 6 Gallon SW DE. or it just better to stick with the Tank water heaters ?

Thanks

That... is a good question.. So here are some talking points.

ON-Demand RV heaters are Propane only because you don't have the Wattage to heat water that fast.

And if you sometimes camp in cold weather.. Since they do not heat without flow... Well that can cause an issue (If I were making one for RV use I'd offer a optional "Do not allow to freeze" heater.. lower wattage. (perhaps 100 electric or alt propane) set to say 40 degrees)

And though I tended to follow warm weather... i got bit by sub freezing a few times... (like 3) the 3rd time I learned how to spend no money (Though a PEX line did freeze.. in the middle of an 8 foot run. the fittings on the ends (Which do not freeze well) were protected so total damage was $0.00)
