Why not just blow out the water lines with an air compressor. It doesn't take much of a size compressor.
No water to freeze anywhere.
I hate to contradict my neighbour down the 401, but that's pretty dangerous advice.
Even a really small compressor can blow most of the water out of the lines, but it takes a pretty good-sized compressor (with large reservoir) to blow all the water out and be safe from freeze damage.
Even a relatively small amount of water droplets left behind can settle down into low spots and cause burst lines or fittings.
You need to have a compressor / reservoir big enough to be able to maintain ~50+ psi indefinitely to safely winterize an RV with just air.
The only thing that causes pipes to burst is water that has nowhere to expand to. If you have virtually all the water out what is left can expand into the places where there is just air. Modern RV plumbing is pretty robust too. The industry is promoting the sale of their products and services. Much of RV winterizing can be filed along with 3000 mile oil changes which are heavily promoted by those that sell and change oil.
