Attaching trim molding

[Home Away...]

On a aluminum skinned trailer with 3/4" plywood sides, do the trim molding screws screw into the edge of the plywood sides? I'm not to that step yet, but I am looking ahead.

Thanks

...on mine, the screw wouldda been right on the edge of the ply...so, I glued an additional section of 3/4ply to the wall, the thickness of the spars, between each spar to help catch the screw...I also predrilled all the screw holes and shot a dab of sealant into each one..............

I had the same question. I am too lazy to cut a bunch more curved plywood pieces to fit in-between each spar for my traditional teardrop shape. I've got it all insulated and wiring run already. I'll probably just screw into the edge of the plies (predrilling holes of course) but it makes me wonder whether those screws are even necessary if I put perpendicular screws in the sides of the trailer. Are screws in both faces of the "L" corner trim necessary?

But boy-howdy, do those pieces add strength.

With sandwich wall construction, you cut off what will become the blocking from the internan skeleton, so it's not a ton of work.
