| Cheap enough that I would go for it and add extra little things such metal box with louvers to shade the a/c from elements, mounting springs, and special switch to reverse the fan to clear dust and debris.
You could add a small squirrel fan to recirrculating the cool air around the cab and blow back thru the duct to clean the A/C daily. After all, the dust is a No. 1 killer of cheap A/Cs.
Edited:
On a second thought, I'd cut up a furnance filter to fit inside of a mental box with a sliding frame. Slide the filter out, shake the debris off, and go! | |
