A vehicle that cost a lot less has options a more expensive vehicle doesnt.
GM cheaping out.
My 2015 frontier sv had dual climate control and back sensors.
And I suspect in 2015, your Frontier did not have a camera mounted on the rear.
Let's see, would I rather have a beeper screaming at me, or a nice view of the wall I am trying to back up to?
I put this in the category of idiot lights versus a gauge: Do I want a light to go off on the dash telling me I just overheated, or would I like to look at a gauge that tells me my engine is running warmer than normal and perhaps I should take a look at it?
I don't get to park my truck in the garage anymore, but when I did, I would back up my truck using the camera to within about 8"-10" of the wall. I knew I could close the garage door then. With the alarms only, I would have either needed to hang a tennis ball from the ceiling or would have found myself getting out and checking every time I parked.
I have had the dual climate control on multiple vehicles. My wife still complains I freeze her when I am driving, so I am not sure that it is that great an option. It sounds good in theory, practically, I just don't see it working that well. I would actually love to see some sort of front/rear zones. Both my 1990 GMC Safari and my 2001 Tahoe had rear ac units, that made the rear much more comfortable, Side to side, not so much. (I know, our truck cabs are not large enough to justify a rear ac, just pointing out the more critical zones as I see it.)
When I was shopping for my truck, I looked at Frontiers and Tacos. My wife's comment on Frontier was it looked like crap, cheap, antiquated, did not even want to wait for a sales person to come out and talk to us. At the Toyota dealership, her only comment was those people are rude, they don't want to sell us a truck.
(In fairness, the first Chevy dealer we went to together, she stated that sales guy is an idiot, doesn't know what he is talking about. The GMC sales guy recognize I knew more about the truck than him and politely let us test drive and didn't flap his gums uselessly.)
Wife's Nissan has got surround cameras and all kinds of alerts and alarms built into the system. Seems to work pretty good. I wouldn't mind that system on my truck, for a reasonable price.
