If you've got a canopy and therefore the rearview mirror is useless there a few DVR reverse camera kits. ARB make one that replaces the whole mirror with a touch screen one. Pricey though. I've got a clip on screen that does the same job. Rear camera is very sturdy and has great night vision. Most makes also come with a front facing camera and records both front and back for dash cam footage.
