Short cut winterizing

[sbowman871]

Just finished up our first weekend of camping. Weather was great, high 70s. On Tuesday, they are calling for a low of 27 with wind, snow, sleet, and all. So I parked my TT at home, outside and did the following. Drained the fresh water, drained the HW heater, drained the low pint drains, and left all faucets open. I think I will be ok for the day or two at or below freezing. Did I miss anything?

There will be water in the lines.

I'd go and get an air compressor (I used 30PSI) and a blowout plug, then go valve by valve (including the toilet and shower) to get the water out... at the minimum.

Do this at your own risk, but I used a pump to get vodka into my city water connection, which I ran through all faucets... then blew out the lines with compressed air. My rig withstood the worst winter in Texas since 1997 pretty well.

Toilet? Shower? Outdoor shower? Put some anti freeze in the traps? Water filter ?
