Can 7-Way Charge Circuit of 2015 Toyota Tacoma be Improved with Heavier Gauge Wire

Question:

I have a cord that I can plug in to my trailer 7 way trailer plug and charge my pickup camper battery on a Toyota Tacoma. Would using an isolater and wiring a charge system to the vehicle alternator provide more charge to the battery?

The wire that your 2015 Toyota Tacoma has that carries the 12 volt accessory circuit iwould be 12 gauge so if you wanted to improve the charging ability of the circuit you could bypass that and run 10 gauge like part # 10-1-1 from the 7-way, through a breaker like part # 9510, optionally a solenoid part # PK5231201 if you want to only have the circuit active when the key is on, and then finally to the positive post of the battery or alternator output post.
