Any reason why this shouldn't work? I was gonna have the metal shop cut the end caps to my roof from my template, then weld/fold lips on top and bottom, then rivet it in place.
Should "work" but a real drag --- (aerodynamically speaking). A long slope would not only cut down on wind resistance...but also improve "limb" resistance as well.
Im going to put in a rounded aerodynamic cap later on the front, I have no need for a rounded ceiling front on the interior, so I'm just going to do flat caps on front and back, then install the aerodynamic one down the road
