You can certainly do that. You'll want to be sure to wire the pin on the vehicle side to correspond with the 12-v power supply pin on the 6-way motorhome trailer connector however. Some 6-ways use the center pin as the brake controller output, some use it as the 12-volt power feed, so you'll want to ensure both sides are wired the same way. Roadmaster offers a purpose-built circuit protected kit for this, part # RM-156-25.
Keep in mind that the circuit is capable of providing a maintenance charge, but it won't charge up a dead battery. You might consider keeping a battery charger like the NOCO # 329-GENIUS5 and a good extension cord handy.
I've linked you to our trailer wiring help article, which includes a diagram showing how a 6-way trailer connector is wired.
