How to convince my parents to let me go camping with my beat guy friend?

Let me preface by saying I'm 17 and graduated high school and am going to college in the fall. I had wanted to do a big camping trip with a few friends but I was talking with my friend last nigh and he was saying we should just go the two of us because it'll be easier and we both are good with outdoors and stuff. I just dont know how to convince my parents to be alright with it. It's not like there's anything going on between me and this guy, I just know that my parents will thinks it's shady were going just te two of us. How can I convince them?
