also how do these mount to the trailer? i cant seem to find any threaded holes that bolts would go through the roof into the unit
I am guessing from your profile that the air conditioner is being installed in your Minuet. If the Minuet wasn't previously equipped with an Air Conditioner, have you installed the A/C in a new opening cut the measured distance from the number one roof bow as specified by Airstream? Once the opening is cut, wood blocks should be cut and installed around the perimeter of the new opening. The air conditioner then installs in that opening, and is secured by the clamping force applied by the bolts that connect the interior and exterior units. The roof vent opening in the Minuet is not
the designated location for the air conditioner so it is not reinforced, and the electric cable is terminated more than three feet to the rear (according to my notes).
You will likely be face with obtaining the interior shroud via a salvage yard. In all probability, you may be faced with modifying the interior shroud to conform to the curves of your Minuet's roof.
Good luck with your project!
