Caravans, motorhomes and camping all come with a multitude of gadgets these days. one of the most entertaining is the remote gubbins that turns a caravan into a remote-control toy vehicle. No more of the yelling and gesticulating as the driver (usually a woman) attempts to manoevre near to the hitch; no more of the grunting and puffing as the operative (usually a man) attempts to heave the hitch onto the tow-ball.
Actually, the gadgetry is even more entertaining. People take longer and don't want to give up.
But at least it is easier on the back.
