Expert Reply:
The Advent Air RV Air Conditioner w/ Air Distribution Box, # ACM135CH requires an opening of 14-¼” by 14-¼”; this is the unofficial industry standard with a tolerance of +/- about a 1/8”. This is for roofs 2-1/2" to 5" thick.
This is the same roof opening dimension to install an air conditioner or vents such as the MaxxFan Deluxe Roof Vent w/ 12V Fan, # MA00-07500K.
