Just had to share this.
My FOTR friends will appreciate this in a ginormous way.
All those random clicking noises inside the RV (electrical), and weird dimming of the lights, and countless other things that were happening... is attributed to the batteries :) R.e.l.i.e.v.e.d!!
Miguel and a friend tested the converter, which we learned, by accident, that we indeed did not have an inverter. Let's just say it's producing more than enough of the needed juice to keep our rig warm and lit, and after replacing only the battery, will leave just enough money in our pocket for the real juice we need to buy at the grocery store.
All my travel buddies, can I get a witness? :)
