Can you jump your 5’er with your truck?
Hi guys, If I’ve seen this before I don’t remember it. Can you jump your 5’er batteries from the truck?

If you are concerned about slides and jacks with dead trailer batteries you could plug trailer umbilical cord into the truck (with truck running) and have enough power to use the jacks and pull in the slides.
All I can tell you is that I've needed to do it with my trailer, and it works for me.
