Reverse Cameras

Hi guys, 

i'm new to caravaniing, I pick it up tomorrow (27th Aug) and am very excited to get out and about with my new toy. Having just spent the best side of £20K on my investment I was wondering if anyone has or is using a rear mounted camera for reversing? I've been driving for many years in different countries so consider myself a good driver. However when I intend to park my caravan at home it is a real tight driveway to get in and thought a camera would help.
