Well when its off there is a bar across the front that the rest of the frame attatches to, with the electrical socket and brake attatchment cable. It is black so it doesnt look like a stupid chunk of metal, but it does ruin the look of the car slightly. But considering it takes about 5 minutes max to take off or put on the frame, and it can actually fit in the boot of the car (although driving would shunt it about your boot, not so good, but it gives an idea of its size) it is practical, and ideal if your someone who doesnt have space to have a trailer lying about when you dont need it, or just doesnt want the hastle of getting the car onto the trailer, taking it off when you get there, hitching up, etc etc. But the A-frame is a very cool idea, the way the car sort of steers along behind you, uses its own lights, and brakes along with the vehicle your using to tow, very cool indeed.
I'm gonna go take some photos and upload them within half an hour or so, I'll do some pictures with the A-frame off, and with it on.
