In most cases, you should plan on installing heavier gauge wires than what you will find on the OEM 7-pin wiring harness. In fact, I wouldn’t recommend using the standard 7-pin RV plug at all for this circuit. The connectors are a poor design for this IMHO.
Also, don’t underestimate the total length of the wire required to connect the DC-DC charger, which should be as close to the battery it’s charging as possible, and the truck battery it will be drawing from (not the alternator!). You’ll be lucky if you can keep the circuit length under 25 feet on a crew cab pickup. Mine is closer to 30 feet.
This is from the Renogy installation guide. The recommendations for my Redarc were similar.
