I have quite a harvest of bugs mainly on the outside edges of the camper but extending in and even all the way across up high (over the cab). There is also a nice pattern of bugs under the overhang somewhat defining the shape of the cab. There is definitely more wind noise with the camper on that with it off.
I wonder why there is such a difference. I have had two trucks and have traveled with the camper for close to 100,000 miles. The camper behind the cab never has any bug splatters. I can drive through heavy rain and it will usually be dry behind the cab. The exception is when I am parked and the water blows in from the sides. There seems to be a cushion of air not only behind the cab but extending forward between the camper and the cab. That is why I conclude that an air deflector is not going to accomplish anything. At least that would seem to be the case for my camper.
The area between the camper and truck bed is also a dead zone. I have access through doors on both sides and I use that area for storage such as extra clothing, paper goods, a long extension cord and a tarp. Everything is always dry and clean in that area.
