Does Pensy allow screens up front, especially ones viewable to the driver? I know in NJ it's illegal and a cop WILL stop you if he sees it. FWIW, regarding your mirrors, here in NJ you don't have to have an interior rearview mirror if you have outside mirrors on both sides of the vehicle.
I found out in PA its illegal. If it came with an interior rear view mirror, it must still have it. I haven't been stopped "yet".
I'm ok for MD
