disco bike rack

I am Landy forum begginer so treat me gentle!
Can anybody please help?
I have a Disco 3 and need a bike rack to carry 2 bikes,
We have a tow bar which removes with a key so it will not take a bracket and we also tow a twin axle caravan. We need a rack that just fits to the car some way.
I have tried to explain to so called "experts " but they just dont understand (thule to name one) .
Is there anyone who has found something to fit their own disco that could piont me in the right direction (this keeping fit lark is so frustrating!)
Cheers.

This is a Thule 3 bike carrier which clamps on to the tow ball.
