I didn't see a reply to the question re shuttle service available to/from the campsite into the town? We, too, have an RV, but not towing a second vehicle.

No there is no shuttle that runs from the campgrounds to town

We've camped several times there and I've never seen a shuttle. Here's a concept, call them.

I did not see a shuttle service when I was there. You are within 3 to 4 miles of the entire town and Battleground. I'm sure that Uber's are available.

Did not see one Call the campground. They did have posts about the bus tours, but we didn't use them. About 3 miles from town.

I didn't see one. We had our other vehicle with us. If you call Gettysburg Campground, I'm sure they can assist you.
