Don, can you give us an update on this deflector? I'm finishing up my Express van and have 2 solar panels on the roof in the same configuration as yours. I can feel the drag on the highway and I am wondering if your deflector has solved your drag problem. Also, when I saw your completed project, the first thing I thought was "a good wind would cause it to lift upwards". Even a sidewind. I'm in CT but I'll be going to the southwest where the winds across the highways can be wild since they travel across the plains for miles.
Hi Ron, It worked very well. We have sold the van and got a camper instead as we plan to do a lot of travel.Dont blame you for leaving CT. We moved away from there.
