When we did winterize we only blew the lines. No flushing no after taste!

I've been draining/blowing out the camper and boat for years without issue. Now yes there is the potential you could get some residual water somewhere, but typically if it's only a little in a low point and has room to expand down the pipe as it freezes it doesn't split the pipe.
I typically drain the FW tank, run the pump/faucets until empty then open 1 faucet at a time and run compressed air into the city water connection. It spits and sputters and blows the water out of the system. Make a couple rounds to each faucet/outlet.
Empty black and gray tanks. Dump a gal of windshield washer juice in each black and gray tank. Done.
Worked in AK sitting outside so it works.
