Peter, the wife can do it & she's very petite, four clicks is enough.
Just to show you here's a photo taken today in the Isle of Wight on the way to the ferry
Just to point out that's a very steep hill & the wife & boys are in the car all so if you look very close between the car & van you can see the vans handbrake isn't on, when towing a caravan around the Isle of Wight you need a good handbrake

.
But to be fair you need a good handbrake to tow full stop
