Any easy way to re-wire the 7-way plug to have the trailer run off the truck batteries without having the key in?? (I swear I read this back when it didn't matter to me) I'm sure nobody has that feeling: " if only I could remember were they saw that!!!" feeling


(besides running 20ft of wire)

thanks

 

just buy a battery for the trailer......set it up to charge off the truck when it's running. hate for you to have dead batteries in your truck when you try to leave.

 

I should have want on... by Sunday I run both batteries dead in the trailer and would like to finish the last day off the truck batteries without leaving the key's on.. ( It takes way to long to re-charge deep cycle batteries so please don't just respond running the truck) but thanks for showing me I need to explain a little better.

 

I think your easiest and a better choice in my book would be to install a solar panel on the roof of the trailer hooked to the deep cycles. Good luck with whatever you do.
