Interior Heater Instead of Winterizing

Throwing this out for info...
I have in the past winterized via pumping rv anti freeze thru all the lines, drains, and tanks. As wife still worked we didn't rv during winter.
She goes part time as of now, and we plan to do some traveling this winter, down to Ga. coast, south Ga, and Fla.
We live in Va, Shenandoah Valley area, and it does get below freezing many times during winter months.
Thinking of just running anti freeze in black/gray tanks, and black/gray drain lines, but all the other plumbing is inside the coach (class c motor home), under sinks, under bed, behind walls, ect. the usual.
Thinking about running several electric space heaters, at around 40 degrees or so, leaving everything inside open for warm air flow.
Want to be able to hit the road without having to de-winterize to leave, and then winterize again upon return.
Any of you out there in rv land do this??? Any problems???
Open to opinions.

You could blow the lines with an air compressor to remove the water from the lines. In here central SC It gets cold, but very few hard freezes. I use a couple of heaters inside to keep things from freezing, and place an incandescent light bulb in next to the water pump. So far so good.

I keep a watch on the weather and if it's only going to freeze for a few hours then I don't bother.

Thanks MS, it does. Heaters are too small, but love the temp sensitive outlets.
One in bedroom area and one in living area each with a decant heater would probably do the trick.
Could blow lines, but would rather keep everything warm enough to keep some items inside that we would normally take in for the winter.
Only outside lines w/o antifreeze would be the cold/hot/fresh water drains, and those I can wrap with some insulation.

If we know we will be taking the coach out for trips during the winter I won't winterize but instead will run one heater upstairs and one in the basement. I use the thermostatic type plugs that will come on and off as the temps get cold. I use two separate outlets with extension cords on separate circuits from the house so I don't overload anything. Works pretty good.

I also have a remote temp monitor for the upstairs and the downstairs and monitor from inside the house.

Thanks jac. My rig is a class c, so no worry about basement. But the temp controlled plug outlets are a definate plus. Wasn't aware they were available. One front and one rear with some decant heaters should do the trick.
If it maintains 40-45 degrees I'll be happy.
Remote temp monitor is also a great idea, something I hadn't thought of. Rig is parked next to house, so it's a great idea.
