Forgive me if this is a dumb question, and I think I know what the answer may be, but I can't seem to confirm it anywhere. Girlfriend and I just purchased our NTU Coleman Bayside a few weeks ago and jave a reservation this weekend to have our first close to home overnight test run. It was winterized by the previous owner and I've left it that way because although it was warm when we bought it, it's been cold ever since . It is supposed to dip below freezing the night we go so I would obviously like to be able to use the furnace, is there a way to do this without dewinterizing the whole system? I'm assuming not, but hoping I'm wrong. We do have a small ceramic heater, but I don't want to rely on it because A) it is just a small, inexpensive one and B) we do not have PUG's or any sort of heat retention yet. Any advice for the new pup owners would be greatly appreciated! On a brighter note, the one problem we found after bringing it home was that the fridge didn't work on AC power. However, after lots of time searching for similar issues had by others, $80 for a new 120v heating element, and 15 minutes of my time to swap it out, it all works!
