winterize the water system?

I have a 23b and was wondering if anyone just removes all the water from the system, to include the hot water tank, with an air compressor hook up to the "city water hook up" on very low pressure as apposed to putting anti-freeze in the system and pumping it throughout? I know that I would have to turn on all the taps to get all the water out and shut them off one at a time. I have two concerns 1.The seals in the pump with it being cavitated and drying out. 2. The hot water tank sitting empty. I just wanted to see if anyone has done this before and had success. My old school training has thought me to leave no pressure in the lines and all the taps open for expansion in case there is water in the lines and to keep no water in the tanks at all. However I think there should be something in pump.

That's why I prefer to blow out the lines and pump in anti-freeze.

Best of both worlds. 15 minutes and I am all done.

Everyone has their own preferences, but I just drain the water heater, run waterpump until empty, blow out my lines through city hookup, and only put anti-freeze in the traps. I've been doing it that way for two different campers for the last 7 seasons without issue in upstate NY. I started doing it that way because my manual said to either blow out the lines or run anti-freeze through the water pump after bypassing drained water heater.

I drain the water heater through the plug and use air pressure to blow out the lines. Our winters in South Texas aren't much to talk about. To make it a little easier I went to Harbor Freight and bought a portable air tank, fitted it with a small pressure regulator, coiling airline and some quick-connects and do the job at the storage lot. One tank of air has been enough to get the job done. Like "Johny" I also pour some anti-freeze into the traps. If I lived where it got really cold I'd probably put some anti in the water lines as well like "doug" does.

Thanks Doug, johnyQ and redhorse1 for the input after this weekends trip I think I will do what Doug did and then after my trip in November I will put the anti-freeze in!
