Lots of things you can do to improve temperatures. Put reflective insulation on the windows and keep the blinds closed, single pain windows are very poor heat/cold barriers. Park in the shade from the afternoon sun. Don't open and close the doors a lot. Use a fan for circulation of air. You do these things and it will improve temperatures. Parking in the shade is the single biggest thing you can do to improve conditions.
If you look at a tour bus you will see as many as 6 A/C units on them.
I'll disagree about opening a vent your letting cool air out and drawing warm air in.
This is good advice. You might also try cleaning your inside filter and getting on the roof, remove the housing, and use a air compressor to blow out the condenser.
Colman Mach Air conditioners are sucky. Poor design.
