Update on our issues
Just before leaving on a 14 day trip our local tech finds that the cabinet switch is bad. PT says to bypass that switch, we don't need it. Then the day before we leave the heat is out again. Drive an hour to our tech to find that the tank temp switch that was replaced last year is bad again. We leave on our trip and I have the switch overnighted to our first stop and have to fix it myself.
Heat is working but cycling too often. Call PT and we get it right. On a positive note it did perform well for the week we just spent dry camping in cold weather.
Looking at the Aqua Hot propane version, I see it sells for 6K while the Twin Temp Junior sells for $3200. You get what you pay for? looks like Newmar went for the lowest bid. So if Newmar drops PT for the future where does that leave us? With a unit I do not trust? I have never discussed my troubles with Newmar, but I think it's time to start griping.
