cold weather and holding tanks
I have a 2015 Montana 3611RL Legacy Edition. It is not cold where I live very often but temperatures are going to be around 25 degrees.I have my camper under a shelter at my house and it has a 50 amp plug. I turned on the heater in the camper on low and turned on my grey,black and fresh water tank heaters.
My question is should I drain all of my tanks and hot water heater to keep it from freezing and put RV antifreeze in or am i ok with what I have already done?
Thanks
for your advice.

When you say turned on your heater, do you mean the furnace? How warm will it get during the day, and how long will it be at 25?

As long as you have heat on inside(Furnace) you will be ok at that temp.

The furnace is on. Temperature in daytime around 45 to 50. It will get down to around 25 at night.
Thanks

If I was not going to use the rig, rather then continuing to run the heater, I would rather drain and winterize.

With tank heat pads and some heat from the propane heater, you should have no problem with anything freezing at only 25 degrees.

We have 4 holding tanks in our 3711fl. The fresh water up front, the galley in the middle. The grey and black in the rear. We have not used the tank heaters at all thinking that the furnace would protect all tanks in the underbelly from freezing. I assumed that our 2016 has the arctic package as did our last 2010. Are we wrong? We live in the Florida Panhandle and it gets in the 20's here some nights. We always empty our black, galley, grey holding tanks and flush the black after every outing but leave about 2/3 fresh water in the tank. Are we safe with what we do?

madeforeachother, if I understand you correctly you are not full timing but use your Montana frequently, being based in the Florida panhandle? If you were having overnight temps in the low 30's I wouldn't worry about having fresh water in your tank. However, if those temps were heading down toward 26 or less I honestly think I would at least drain it.
Problem with these predicted overnight temps in Florida is that sometimes they miss the mark. You would hate for them to predict is was going to get down to 29 degrees and then due to a change in overnight cloud cover the tempt dipped to 22 instead.

Thanks for your input. We never had any problems with the last 2010 Montana because the underbelly was heated by the onboard furnace and temps were in the mid to upper 20's. The tank heaters are new to us and there are only three switches in the control panel and they are not labeled which switch heats what tank. We were told by dealer that the three switches are for the three rear service tanks and the front fresh water tank is heated by the furnace which is right over the fresh water tank. We want to believe the dealer but they have been wrong in the past and we would rather trust our fellow MOC'ers for their views.

Running your furnace will keep the tanks warm enough not to freeze. the tank heaters were added to give it a zero degree rating. Also your fresh water tank is in the rear. from front to back the tank lineup is Galley grey, bathroom grey, black, then fresh in the rear.

Thanks for the heads up on the tank heaters. We have the 2016 3711fl and the tank in the front under the living room is the only tank with a 1/2 inch capped pipe drain exposed under the belly, so we thought that has to be the fresh water tank. The other tanks are drained by the drain knife valves. Do you think Keystone changed the tank locations in the 2016 model?
