If you are leeping the standard tow-bar then fit a Dixon Bates combined pin/ball hitch, known as the @pinball Wizard'
The Mayploe copy is about £50 in Towsure.
I'd found most if not all towrope hooks are secure on the pin, plus strops will fit in in nicely and the breakawy cable on the 'van too.
Plus if you leave the pin in the glovebox when it's hitched they are also a good fit on the Alko-Kober hitch-stabiliser that I love so dearly (not
).
