This is a pretty cheap unit with a 2.4" screen. Not going to see much on that unless it is mounted right in front of you. I think my money is better off being spent on a better quality unit.

I have driven a street sweeper with a setup similar to Tom's RV. The one in the sweeper would allow you to turn it on as a rear view camera. That is what gave me the idea to buy one and hook it up to a switch. Those units are of a high quality and I am sure work much better than this unit.

I took it back today and picked up some Polk Audio 6 1/2" speakers for the rear. I will enjoy them much more.

Maybe next sat. I will heat up the garage and install them. I have been wanting to take out the back seat anyways. I helped Breezy put his back together when he changed his rear speakers so I know what I'm in for.
