I use RainX and have one wiper on, tucked down lower than stock, out of the wind. I have been procrastinating disconnecting the other wiper motor. But the benefits (though very tiny) are three fold: (1) I have observed differences in droplet patterns on my windshield with/without the wipers so I think it does something but I don't make pretense to it being a much of a something; (2) RainX allows me to use the one blade less than I would and still be safe, which saves battery power for my alternator cut-off, deep-cycle, plug-in setup; and (3) disconnecting the unused motor will likely save a little more power. If the motor turns out to be a little weighty and easier to remove/replace than to simply cut power to, then I will maybe remove the un-needed motor altogether.
All that said, I redesigned my airdam and reinstalled it yesterday. Now it does not scrape and I expect real freeway gains from that, unlike the near-fantasy gains my wiper delete provides.
