Same here. Never a problem. And my son, who worked in the RV business for 7 years told me that even the mechanics in his shop who winterize campers for a living said people are wasting money and time on this unnecessary chore.
Keep in mind, many people just pay the shop to take care of this because they don't want to deal with it. If they knew about just purging the system with air they might not take their unit to a shop.
No matter what type of RV you have, you can purge every line with air making sure you're good to go for the winter. I do the same thing with my irrigation system, and this is vital so that no pipes, valves, or sprinkler heads break.
And need to mention that even my RV manual gives me the option for both methods, showing how to do either one.
