I have a toyhauler that I use during winter quite often as well. You may get some negatives around my suggestion, but I have done it for many years and no issues. I use compressed air to blow out all my lines when I return from a trip. You can purchase a quick connect air fitting that screws in to city water inlet and using around 30-50 lbs of pressure “blow out those lines one at a time. It only takes me about 15-20 minutes and I’m good to go for any weather. I do however use about a gallon of RV antifreeze as well to pour down traps etc, to ensure tank valves don’t freeze and traps are protected as well. I use shark bite fittings on lots of residential stuff, but a sharkbite fitting would concern me on a trailer due to constant road vibration and other factors.
