I paid more money to get just the navigation without the moonroof, which where and likely still are a package deal. My experience as an auto tech is that moonroofs are noisy, leak water, and screw things up. I didn't order the Platinum version because its towing rating was lower and 20" wheels have a lousy ride, get worse fuel economy, and bend too easily.
Most city dealers do not stock the 157" or longer half-tons because most spec houses don't have long enough garages to park them in and so the longer wheelbase trucks do not sell as well, according to my Ford sales manager who shared that tidbit with me years ago.
I didn't have the dealer wash my truck because their car wash isn't touchless and my level of dirt turns traditional car washes into sandpaper for the next two dozens cars that go through.
I have not had any problems with the moon roofs on my modern vehicles, but have on the older cars, even when new. However, I never use them and have no desire to pay for them, if practical. I just have no need for something like this. My last car, a 2008 Subaru Outback XT, had two of them and the only time I opened them was to test to make sure they worked.
I also do not like factory nav systems, but had to purchase it with my new Ram from a dealers lot that was out of state. Actually my truck is fairly optioned out and the nav unit was the only thing I did not want and all of the other things I wanted were there, including colors, snow plow prep (220 amp alternator), block heater, clearance lights, aux. switch bank, etc., etc. But this 2015 truck allowed for a $2500 discount over a 2016 that was an additional $1000 higher on top of that. So I am okay with the nav unit

But I have my Garmin installed on a stalk by the drivers seat.
I sure miss the 15" - 17" wheels where the tire added a lot to suspension characteristics. I have 18" wheels on my new Ram 2500 diesel, CC, 4WD- the smallest aluminum wheel diameter available, and told all dealers I would not accept wheels any larger. As far as I am concerned, low profile tires and large diameter wheels are only appropriate on performance vehicles on the track with modified suspensions, where they can truly take advantage of the shorter, stiffer sidewall. Street vehicles typically can't as long as they are obeying traffic regulations and provide a harsher ride. I don't get it. Especially on a heavy duty truck.
A friend has a BMW 33x that cost ~ $73k and it is a truly beautiful car I admire whenever I see it. He hit a pot hole in town with a RR wheel after avoiding it with the front wheels and bent the wheel. I told him I am not concerned about pot holes as my wheels just drive over or through them.
We will be moving into our custom built home in four to six weeks and that builtin garage is just a tad short for my new truck with the winch bumper and winch. Well, I could probably squeeze it in but the truck will fit nicely in the shop, along with the tractor..
