In this video I describe how I install a reversing camera in a Vauxhall Vivaro campervan conversion (See links below for items used). The Vivaro has solid rear doors with no windows so reversing can sometimes be awkward when reversing close to other vehicles or tight parking spaces etc so having the addition of a reversing camera makes a world of difference and allows reversing with more confidence that you aren't about to bump in to anything.
