I've been ramped a couple of times in South Florida, maybe more and I just can't remember. Even though I've flown some 135, I've only been ramped flying part 91, and only AT NIGHT. It's been probably 10 years since the last one, and they both happened within a couple of years.
It was never an issue because yes, all the documentation was correct and handy - and that's all they really seemed to focus on. If I had had a nav light/beacon out it might have been more interesting, I suppose.
The fact that I've been ramped at night may have something to do with South Florida peculiarities - I know a number of airplanes have been stolen from OPF, where FAA ramped me. At HWO there is a Border Patrol headquarters, and I was ramped there as part of what seemed to be a training exercise involving a dog - the dog was a little excitable (green?) and my buddy barked at the handler because he let the dog jump up and scratch at the airplane with his nails.
I was also at EYW once (daytime) and saw an Inspector there that I had dealt with before - he was doing ramp checks but left me alone. I had sort of butted heads with him - maybe he didn't want to stir me up again?
