Good evening everyone. Couple of questions if possible. Have a 30' Travel Trailer that I purchased new in May. Thinking about just leaving it at the RV Park its been at for the summer, the whole year so we can use in the fall and winter. Question.. can this be done ? How do you keep pipes from freezing ? Do you leave the heat on a low temperature all week when not there to keep things from freezing ? If so how long does 2 propane tanks last using the heater during the week when no one is there ? That's a lot of questions but I think you see where I am going with this. Any suggestions would be appreciated. Thanks
