I have to mildly disagree with my esteemed colleagues. There is much more wind noise in a truck, compared to a passenger car, and although it can be reduced, it cannot be eliminated. Now, I have a Tacoma, perhaps those folks in a larger, better insulated Tundras do have less noise to begin with. In a car I could hardly hear the engine noise, in my truck it is inescapable.
I don't think the camper contributed too much extra noise, but it did add some. I did add a fairing/deflector which helped a bit, but I added it to reduce wind gust affects on the camper & handling, and it was successful in that.
All that said, I used to listen to audio books while traveling in my car. I simply cannot do that now. Maybe some of the issue is my advanced age and thus my hearing acuity is less than when I was younger. But when the book reader puts any character in the words and speaks a soft passage, I lose what is being said. It's just too hard to try to follow the plot.
I bought an XM satellite radio and listen to that while driving. I can enjoyably listen to classical music, even the soft passages, without issue. I can listen to talk radio (very rarely, perhaps to catch up on the news on a long trip) and hear everything that is being said clearly. I enjoy listening to baseball games on the satellite radio. I've had to give up listening to books.
Please don't be tempted to use ear buds or phones while driving. It is illegal most places because it is dangerous to cut yourself off from what is happening around you - you can't hear sirens, big trucks or fast cars overtaking you, or even engine noises that might indicate something is mechanically wrong (or coming lose on your camper.) It is easy to get lost in the world the audio book creates, don't make that worse by using head phones.
