I put a 24 volt camera system on my 5 ton from rearviewsafety.com. The system is great, highly recommend it. I started with one backup camera and their 7" monitor. Have since added a right side camera that can spot a small car in the blind spot. If it were not for my buddy riding shotgun in October, when returning from the Georgia Rally on the Interstate loop in Atlanta, and needing to make a lane change, I would have run over a small car that was maintaining position abeam my front wheel, totally out of view of mirrors and driver. Also added a forward facing camera mounted on the front of the hood to see exactly where the right side of the winch bumper is. You just press a switch on the monitor to scroll through camera images. I normally leave the rear view image on the entire time while driving. The folks at Rear View Safety have been very helpful with selection of cameras - they have quite a selection, different angles of view, some can be mirrored, etc., as well as no problems in returning the wrong extension cords ordered. This is professional, very well built hardware, roughly $180 for the original camera and monitor. Extra cameras were about $100 apiece. Cheers!
