That's the same towbar as mine. I have a motor mover,so hitching up is a lot easier that reversing. The san neck is held in place by two bolts. If you take them off,you can remove the swan neck if you want. I ended up leaving it on. As you say very good towcar. I tow a challenger sport 544,1435Kg fully loaded.
I have been following this and other towing threads for some time and recently decided to fit a towbar for a trailer. I bought one which I have not seen mentioned here or the other forum for £69.50 including delivery from Italy, which took less than a week. Fitting is simple and takes less than half an hour (excluding electrics). I assume all towbars are fitted the same way using the 8 threaded holes in the chassis. I have not yet decided on which electrics to fit.http://www.ebay.co.uk/itm/261529536862?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
