Yes. Leave it winterized and use windshield fluid to flush. Use bottled water for drinking. Use disposal eating utensils as much as possible. A little water mixed with the pink stuff in grey tank is ok. Sometimes it is two days until we can unwinterize. When camping in really cold we leave slides in as much as possible. Makes a huge difference and of course a lot easier then in truck stop or rest area. Run generator fairly steady and supplement heat with space heaters as tanks are winterized anyway so no need to worry about getting heat to them. Couple of bottle of windshield washer and bottled water and it works well. Winterize as others do as soon as home but do drain tanks when temps start getting below freezing. Leave valves open and then just add pink stuff when home. I winterized on April 1. !0 bucks of pink stuff is cheap insurance.
