Will The Furrion 7-Way Vehicle Power Adapter Help Charge The Trailer Battery

Question:

I have a alliance avenue Im pulling with a 2022 Chevy Silverado hd. Im running the 12 volt fridge and the furion camera with back and side view plus rest of camper while driving which drains the RV battery. Will this part also put more voltage to battery or does it just put more to running light feed

Newer GM trucks like your 2022 Chevy Silverado have PWM wiring, which is essentially sending a pulse of voltage through the line instead of constant power. The 7-Way Vehicle Power Adapter for Furrion RV Observation Camera # FR87PR just has a jumper wire from the 12v accessory pin to the running light circuit for a constant 12v feed. This was designed because cameras systems weren't able to function with pulsing voltage. For this to charge the trailer battery you would need a line running from the 12v accessory line in your junction box to the battery, but even then it's most likely not going to be able to keep up with the demand from a fridge and other accessories.

To maintain the battery of the trailer while driving you would really need a charger like the Redarc In-Vehicle BCDC Battery Charger # RED96FR. This would charge the trailer battery from the vehicle battery, which is being charged by the alternator. This specific charger is rated for 12 amps to charge the trailer battery better than just the little trickle charge you'd get through the 7-way. Installation will require you to pick up two fuses # RED76FR as well to protect your system.
