I'd recommend using the 12-v charge line from the motorhome to provide a maintenance charge to the battery of the Yukon. You can easily do this by installing a Roadmaster Charge Line Kit, part # RM-156-25. I've linked to a demonstration video for the kit.
Keep in mind that you'll still need to stop every 4 hours or so and run the vehicle for a few minutes, as the charge line kit won't have the ability to fully charge the battery.
