Tankless water heater

Had a tanked propane/electric heater.  Changed trailer and got a tankless.  I'd change back in a heartbeat.  Sure you get unlimited water but it costs you in propane.  Always changing  tanks.  Takes longer to get water.  Every time you touch the hot faucet your heater fires up.  Think how many times you turn on the hot for just a few seconds,  like rinsing dishes or accidentally.  Mine does not have a backup heater for freezing weather and they will freeze and bust or you drain them every time you travel in freezing weather,  Each to his own but I do not like them.
