As you can see from the map the road goes both in front of and behind the campsite. We had the pleasure of camping closest to the hillside so when the trucks opened up their belly’s to go up the hillside at 6am we heard them loud and clear. Same thing when they use their engines to brake going down the hill. If you have an RV I’m sure it’s great as it deadens some of the sound but I certainly felt like I was camped next to a city highway as a vagabond. Zero stars
