Any tips on the tankless water heater

Makes sense that there is mixed results with RV's. Tankless works on flow rate vs temperature rise. The higher the flow rate, the more burner, or burner(s) will activate and heat the water. The other part of the equation is the temperature rise. You need a good flow rate and high rate of heat for a temp rise from 50-120 degrees in a few inches. The problem with an RV application is the inconsistency of flow rate and temperature at different campgrounds. Sounds like it works for some, not for others. I am all for technology but to me good old fashioned lp tank heater works fine as it's not subject to variances. I have tankless in my house and it's saved us a lot of money. We are on a well and that will kill a conventional tank via minerals. With tankless there is no storage area to allow mineral accumulation. The other upside is that tankless is only "on" when there is water flow as opposed to a conventional tank that heats water all day. But with a 10 or 20 gal rv water heater it's as easy as turning it on an off. I don't see a big upside over a standard rv tank setup. And a huge downside unless conditions are optimum.
