I'm assuming its a newer unit because your saying there is no access from inside. I had a friend with a newer unit experiencing little airflow out the vents so they took off one of the vents to see if there was any obstruction they noticed that the lip on the vent itself was about an inch tall. This made the air have to ramp up over the top then down and out the vent. They replaced all of the vents with ones with a smaller lip that protruded into the duct and the airflow was good afterward and the rig cooled much better. You might pull a vent down and see if that could be an issue on yours. Also check each vent at the end and be sure there is a block installed to stop the flow at the end of the run. Some have reported that the air at the end of the run went into the front cap or attic area.
Inspect the ducting by removing vents and sticking your phone in the duct and taking a picture. That is how I checked mine and decided to block the end of each run.
