I ran furring strips down the length of the trailer and used that space to put another inch of insulation and then I screwed the Luan Plywood into the strips. I screwed the furring strips into the ceiling "beams" with self tapping screws.
How long were your screws into the furring strips? And did you have any problems with the thin Luan Plywood splitting?
My furring strips aren't going anywhere. They have been attached and should withstand doomsday! It's just that thin 5mm plywood that got me concerned
I'll see if I can find the screws I used and get the details, but I believe they were just 1/2 countersink wood screws going into the furring strips every 12 inches. As I recall, I pre-drilled and then used a hand screw driver the last part of the drive just to get the depth right (barely below flush with the surface). If you pre-drill, you should have no issues with splitting. If you use an electric drill with a screw driver bit and are not careful, you can drive right through that Luan.
BTW... you probably already know this, but paint the Luan before you install it. It will require some Kiltz to seal it and then a good coat of whatever paint you choose. It will be a huge mess trying to paint a ceiling after it is up. I learned that from my first CTC build. :-)
Also, if you want a little extra bonding, just run a bead of Liquid Nails down the furring strip before you put the Luan up. I did not do that because I figure the amount of screws I put in was sufficient, I had foil tape in the way (sealed the insulation air tight) , and I also knew I had cabinets and walls going in that would further support the ceiling since they are flush to the ceiling . Just some thoughts.
When I installed the Luan, I also ran a temporary rail down each side (1*2) that the Luan rested on in place with just on 2*4 cut to the right length in the middle holding the center while I positioned it into place. Made it an easy 1 man job. I moved the rails (held on with 4 screws into the plywood side) down as I went). If you look closely on the sides you will see the temporary rails.
