I would take a picture of mine, but it's in the depths of the garage somewhere. I built the top rack as Gary suggested. Works great.
However I seldom use it. It only takes me a couple of trips using my rolling stool as a sort of a dolly or just carrying things. Everything is so light these days, except the cart; it may be the heaviest piece of gear I own.
All I have are two Bose Compacts, a keyboard bag and ultra-light aluminum tube stand that simply folds open or closed. Just about everywhere I play it's only a few steps from car to stage.
Mic boom is on the stand already. Cables are in the bags.
I do use the cart at Barksdale AFB and a couple of other venues where a longer carry is involved.
I can be playing within 10 minutes of arrival, although I allow at least 30 minutes just in case.
