You didn't mention if you have double barn doors or a tilt ramp ...
An alternate direction... have barn doors. Picked up a foam insulation board ... 2" x 4' x 8' and trimmed to fit (held in place by friction only).... just folding back the right door and secured in place. Using a portable shelf... secured a window a/c unit and cut out the opening... keeping the trailer intact.
Bacon should be capitalized as a pronoun for pork!
