Our 3791RD has been sitting at the dealers service dept for nearly 2 months now waiting for parts to come in for warranty work (I cannot believe how slow Keystone is to provide parts).
I stopped by to get something out of the 5er and the batteries were totally dead they left the battery switch on while parked and completely drained the batteries, hopefully they did not damage them.
I got to thinking while I have a portable generator that would take a while to charge the batteries especially from dead I got to thinking would a heavy duty Jump starter work to help out low batteries.
My question is has anyone ever tried using a portable heavy duty jump starter to assist in operating your Slides or Jacks?
I was thinking this might do the job 3400 Peak Amps. If something like this would work it would make a great back up option.
Note: I realize this likely would not work with totally dead batteries but maybe on batteries that have some juice left
