Morning. We too had some holes in the ceiling from the old Dometic air distribution box when we installed the Houghton ADB. We are using a while vinyl repair patch (tube) to fill the holes. We did not install the 8 screws at the edge of the Houghton ADB. How are you handling it?

Just wondering about how the ceiling looks after installing the Houghton plenum. It looks like the old Dometic left some holes and outline because the Houghton plenum is smaller. Do you find that quite noticeable?
