Sort-a winterize

[retiredtraveler]

My wife and own a 1998 HR Endeavor DP. The tanks appear to be insulated. Now that we are retired we plan not to see the snow that invades CT every year. We are planning to go south for the winter.
Question is this: We are bringing Mother-in-law to Europe for a couple of weeks in November. It generally gets into the 20's or lower here at that time. Of course we will dump the tanks, but can I just drain the low system drain and put antifreeze in the drains and let the outlets be open and pour a bit of anti freeze in the drains?
I do have an air compressor but it gives out a lot of air pressure when needed but very low volume. Do I need to buy an air tank to get some volume to blow out the system?
Any replies are appreciated.

Winterized. If you do not have a hot water by pass and this is a one time think just put the extra antifreeze in.

If it were me, I'd have it winterized. Take your trip without worrying about it.

Trouble is there may be water still in the pump and filters and in toilet valves (and the water heater)that low draining doesn't get rid of and unless you provide some sort of heating to critical parts of the MH, these areas will freeze regardless of insulation

Just to be cautious, we would drain everything...... Why not take it to a dealer that will winterize for you.....just this once? Would save you some angst and maybe lots of money later on.
