Winterizing 2005 Adventurer per Manual

After draining and blowing out all waterlines, the owner's manual says to operate the water heater by-pass valve, then run RV antifreeze through the antifreeze intake tube, through the cold water lines. It says nothing about the hot water lines. Shouldn't both lines have antifreeze?

I'm not an expert, but if all lines are blown out, and you took the plug out of the water heater, why would you need to add anti freeze? Did you remove the water filter under the sink and drain the water out of it?
I would think the only place needing anti freeze would be the drains. I could be wrong but just trying

Yes, you need to pump the anti-freeze through the hot lines as well. Sometimes those manuals assume you'll know to do the same for both lines. And don't forget any sprayer nozzles, outside faucets, icemakers, dishwashers or washers...if you have them.

The reason for the anti-freeze step is to avoid any split lines due to water collecting in low points in the lines, freezing & then splitting the hose. Some people don't do this, but $10 worth of anti-freeze is cheap insurance against what could be a costly leak later.
