Hereís hoping youíve already winterized your rig, because you mention you live in Northern Indiana. Camping where temperatures can be below freezing is always a concern for plumbing, because so much of your RV plumbing is outside of the living areas, and/or inside walls. Just because you may be able to keep the living quarters at a comfortable temperature for yourselves, does not mean freezing temperatures canít cause damage to plumbing parts. Besides....using your RV furnace uses an excessive amount of propane. It draws heavily from both your 12 volt system and your propane. Running out of either can make camping rather uncomfortable. Then, thereís where are you planning on staying at that time of year.
Iím sure others will chime in, but these are just some of my thoughts to consider.
