Add a modest solar charging system and leave the batteries in place.
That would be my vote if you have sunlight on the camper. Make sure it has a quality charge controller so you don't fry the batteries by too high of a voltage all the time.
If it is stored under cover, I would go the disconnect route. Add a disconnect in the system somewhere, and completely power down the camper. 2 months won't drain a battery all that much. If you have a good charge setup on the truck, it will get the battery in shape while driving home. Plus time plugged in while provisioning the camper at home should suffice before you head out.
