If your water pipes are inside the coach (not underneath) I would simply heat the coach for the night, with either its own furnace or an electric heater, opening any cabinets that have pipes behind them. If the plumbing is exposed under the van I'd open the low-point drains and all the faucets (but still heat in interior). Most of the water will be out of the pipes, and if any freezes, it'll be unlikely to fracture them.
Also, If the tanks are empty, I'd dump bit of RV antifreeze down each of the drains, mostly so that the dump valves are coated in antifreeze.
