replacing roof and decking
replacing my trailer epdm roof and decking. I am wondering if 3/8 ext. LUAN would be sufficient or do I need to look at other plywood. do not want to go back with OSB.

AFAIK, there is no exterior graded Luan sheet goods. It all has an interior compliant glue. As was stated, use an exterior grade 3/8" Plywood. It should be stamped "BCX" or similar. The first two letters are the grade of finish plies and the last denotes exterior grade. A surface filler is typically used on screw indentations and seams, that keeps the EPDM from resting into a crease or hole.
