Planning on installing Solar Panels on my 2016 Elkridge E-292. Spoke to a factory guy who stated the roof on the 2016 E-292 is basically 4ft x roof with aluminum c channel frames with styrofoam in the center and no ribs in between. Have any of you out there installed solar on your E-292? Is my description of the roof accurate? Next time I climb up on the roof I will take my stud finder and see what I can find in between the obvious rib locations. Much whiter than the rest of the roof lines go across every 4 feet.
