I have seen water pipes freeze 20' from an exterior wall in a well insulated brick and mortar house at -10. All it takes is a pinhole of air making it thru the insulation to freeze a system solid. An RV is far from a permanent structure and you are likely facing a losing battle to keep your water flowing in an RV in conditions consistently below zero. Heated hoses, heat tape, and placing a heat source inside the underbelly might help but in my opinion I would blow out my water lines, disconnect from the water spiket and use water out of a 5 gal container in the galley and a couple gal jugs in the bathroom to flush with until the cold snap passes.
We have camped for several days at temps near or below zero using the above method and using CG facilities except at night. We had no issues with heating the cabin and were able to cook, use the sinks, and use the toilet.
The drip drip drip will help since moving water will resist freezing a little, but skirts around a camper only helps so much. Insulate the skirts and place a heat source behind the skirt along with heat tape and heated hose will give you a better chance but at -10 you may well be facing a losing battle.
