De-winterizing for trip...question

My husband and I are leaving tomorrow for a 10 day trip to Florida.  Right now we are winterized. Our first day out we are driving to Emporia, VA and we are planning to de-winterize once we are there.  I just checked the temps and it will be freezing at night.  Since we will be running the heater is if ok to de-winterize or should we wait until we get to GA?

We camped last weekend over the holiday when it got down to 26 degrees and had no problems.  We disconnected our water hose from the Pod just in case, though, which was good since the water in it did freeze up.

We went to a winterizing class at our dealership and they advised that it would take two full days of the temp staying below freezing before you would incur any damage. You should be fine.

Well, the pex lines are near indestructable. And if your water heater is turned on, it's not going to freeze.. And if it's not it will take several days at end of season "freezing temps" to freeze 6 gallons.

That leaves the p traps under the sink and the shower, and of course your holding tanks. Guessing most won't see "above freezing" go overnight to 20 below for days on end.. a couple days "below freezing", actually shouldn't hurt anything. If worried, pour some anti freeze in the sink and shower traps.

At 28 - 30 degrees, it would take many days to freeze up the contents of the holding tanks. And as long as they are not mostly "full" even them freezing won't hurt anything. Polypro does just fine at freezing temps, just don't want the contents swelling with the freeze.

Any plastic parts not made of pex have a good chance of freeze cracking (drain points, waste valves,etc.). Even if the interior is kept above freezing, any valves below the Pod could be badly damaged. I can't believe that a dealership in Vermont would tell you that freeze up would take two days to do any damage. Maybe they wanted to sell you a new Pod?
