MDRob, you've gotta get the rear view camera, especially if you pull a trailor. You can use the Z1 split screen to show both the rear cam and map screen at the same time. That way you can keep an eye on your trailor while driving. My only suggestion would be to go with another camera instead of the Pioneer model. It's okay, but more sutied for an RV where it can be mounted up really high to look down. Again, it's not a bad camera but you can find smaller models out there that are better. That is the ONLY thing that I would have done different.
Do you have the factory sub-woofer? If so, you'll be impressed with how well the Z1 (with no additional amps) boost the factory speakersand sub.
Send me an email and I will send you a list of everything that you'll need for your install, including the module for your steering wheel controls.
