When the tow vehicle gets there to take you to a repair facility, or your tow vehicle returns you can jump start the slide.
My battery is good for one night
Also, there is a manual override on the slide but ... May take two VERY BIG men to operate it (mine does)
Now might be a good time to pick up a small portable generator.. Depending on teh size of your converter 1,000 to 2,000 watt range.. Honda or Yahama inverter jobs are best,,, But even the 2-cycle 900 watt job from Harbor Freight should run a 45 watt converter to re-charge batteries (takes a full kilowatt, true Kilowatt to run an 80 amp, a Honda EU-1000i is not a true Kilowatt and will not do it I am told)
