Why would I buy a Master's?

The Master is a mid-range Black Jack with almost all the features. If these things are important to you, buy it.

I don’t need the remote control, ball bearing worm drive and extra lift capacity the Maxi offers.
My caravan\trailer is a good size, say 3,000-4000kg with a tow ball weight of 250-400kg.
I have room to install the Black Jack Clamp on my chassis A-frame.
I really like the folding foot option that comes with the Master
