Switch to Prevent Trailer Battery From Draining Parked Tow Vehicle Battery  

Updated 03/18/2021 | Published 03/16/2021

Question:

I am going to rent out a vintage camper with a converter and onboard battery. I have a battery isolation solenoid in my tow vehicle. What should I get to allow others to use the charge of their vehicle without draining their own battery when hooked up and parked?

I'd just install a switch on the circuit on the trailer side like with # PK34213 so that you can prevent the trailer from drawing from the tow vehicle when parked. Basically it would allow you to open or close the circuit to the vehicle side whenever needed.
