It's a little busy with off roaders even in winter but you can drive to them in basically any vehicle unless it's completely shitty out, plus they usually have a shitter. The well pumps are probably closed in winter due to freezing so you'd have to bring your own water to the more back country sites but several have completely normal road access.
Biggest thing for winter camping is keeping off of cold ground. Make sure you are sitting, kneeling, etc. on some kind of insulation. Foam sleeping or sitting pad, a square of reflectix, piece of neoprene, etc. Avoid touching things with bare skin, getting sweaty etc.
The hardest part imo in winter is if you are sitting around when it's dark at 7pm with nothing to do but wait out a long night. Personally I would find some activity during the day, a good hike or something, that's going to wear you out a bit and ensure you'll actually go to sleep. Get to camp with a couple hours of daylight to set up, build a comfy fire (I would bring local wood in from a camp store or roadside spot, a lot of what's on the ground now is probably wet and frozen, can be used but it's more trouble than its worth for a weekender) and make a dinner. Enjoy a nice cold night out. Have yourself an airplane bottle of something, sleep, and wake up with the sun. If you're going to try your current sleep system I would bring extra layers and blankets and keep them in the tent even if you don't use them. It will be a real bitch to go get them from the car at 2 am.
In the morning, start your stove or whatever for a warm morning beverage. Tea, hot coco, instant coffee whatever. Then flip your sleep bag inside out and cover yourself like a blanket to stay warm and let your body heat drive moisture out of the bag. Enjoy your drink, eat something quick for breakfast if you feel like it, and start moving.
