The heat tape sounds good if it freezes. I wonder how many gallons of antifreeze it would take to fill the drain pipes when just starting out? At least enough to give me a break...
I thought we wouldn't have to do anything with water but my wife told me she wasn't about to sleep in a WalMart lot without the potty.
On another note, I finished building my new bed to replace the sofa. Some guy paid me $80 for the sofa; he is tricking out an old van. I'll see if I can find some place to drop the photos so you can see how I did the project. We have a weekend trip coming up to try out the new sleeping arrangements!
