Hi, my kids want me to lug their bikes around on the back of my disco td5, does anyone know of a decent carrier type that would do the job (without damaging the vehicle), also may need info on where to obtain and connect loom for electrics if I have to have a lighting / no.plate board fitted behind the bikes, thats assuming there is a ready made socket to plug into somewhere at the back end of the vehicle. Any advice much appreciated.... .
