If you have the ability I would blow the lines prior to leaving just as a precaution.
Yep, and don't forget about making sure the tanks are dumped.
I made the mistake of thinking I could do the 3 hour drive home and dump my black and grey at the local sani-dump. Good thing I dumped the fresh water and blew the lines before we headed home.
It was 45 at the coast by the time we got home the temperature had dropped to 22. I got to the sani-dump and the dump valves had fozen up.
It took me the whole next day to get enough heat into the belly pan of my old Airstream to thaw them up so I could get them emptied. Never again I'll spend the extra 1/2 hour going out of my way to dump them at the coast.
