Nothing wrong with your method. Lots of folks winterize their water lines using the compressed air method. The only drawback with this method is, sometimes water lines may have dips in them, or low spots and all the water may not successfully extract, subject to freezing. However, with all pressure off and space for ice to expand, nothing ever gets damaged.
Any water droplets left in the system will freeze. Depending upon where those droplets remain could potentially freeze and of course, any water that freezes will expand. If those droplets are in water valves, or joints, it's possible they could expand enough to cause leaks.
Using RV antifreeze guarantees that all water in the system is replaced with something that will not freeze (or should I say ... "expand" because RV antifreeze still freezes), including the water pump itself. All water, droplets, everything is displaced with RV antifreeze.
As stated, blowing air works, and is successful for lots of folks. And quite frankly, I've not heard of anyone having any problems after using the blow method.
Two travel trailers ago, I used the blow method. To my sad disappointment though, the outside shower head on the end of the hose still split over the winter. Replacing it was easy, but after that I returned back to the Antifreeze method and been doing so ever since.
