AC ducting?

How do I determine if my AC ducting is collapsed? I get very little air flow. It is 95 outside and 84 inside with both ac's running. I'm thinking it should do better.
I removed both living room intake grille's and removed the filter. air flow did not increase by much. I'm a 1000 miles from my dealer (Cocoa Beach Camping World) and going further. I"m full time so I can't just bring it someplace and wait.

When you have the filter out, if you can't put a 1&1/2" piece of PVC pipe in there then it's collapsed and you need to. For me it was one 9" piece on each side of the vents. Also, if you take your supply vents out you'll see they project up into the ductwork and if you cut those back you'll also increase the flow.
