Temps here are so nice, we are going to head out this week. My question/concern, should I de-winterize? I have the Sierra 355QBQ, it has a covered underbelly and heaters. Will it be ok, if/when it does dip below freezing? Or should I wait and just bring some jugs of water for use?

honestly but only my opinion unless its below zero for a few days you would not have a problem .

20 degrees for 8 hours and the 60' during the day I would trust myself .

ultimately you need to be the judge

I do not actually winterize my unit until the first week of Jan each year. During Oct, Nov & Dec I just drain the lines/tanks & leave all faucets open between uses.
I also un-winterized in the beginning of March every year.
I run beach through the lines, flush a second time with fresh water, drain the lines & tanks & again leave all faucets open.
Never had a problem over 20 yrs & four campers.
We’ll be heading out for the first trip of the year next week.

If you follow this you should really not have a problem even if the temps drop for a short period of time.
