£195 and I think it is screwed on but not sure. I can open and close the door, but using a grey plumber tube thing over the door to help protect the awning, it has taken a bit of trial and error to work out pitching the awning. I have been told you can also use a tennis ball on the edge of the door. They angled the rail to point up to help with the low clearance over the door. I tried the magnetic attachment but it failed which I why I paid the extra. I have also since had the electric hook up moved from under the back of the vehicle to under the bonnet, no more lying on the floor in the rain!!!
