Google lets you download maps to your phone so you're not dependent on cell towers. Northern NH is pretty spotty so I started with that now I have basically the whole northeast down to DC on my phone.
The reason is cost. They run e-fans on the 1500s to help meet MPG targets. HD trucks aren't subject to CAFE regulations so they don't care. They don't run them because they're better.
AC on my 2003 with a mechanical clutch fan was garbage when not moving. Electric fans are massively superior. No way that one shitty fan that can be stopped by a fried clutch that is dependent on engine RPM can outflow a pair of electronic fans. And I cannot recall hearing of an electronic fan failure on these trucks.
GPS uses a tiny amount of data. I used to use my phone constantly when traveling and never saw an appreciable use of data. And you're gonna pay all that money for a database that is inaccurate/outdated.
Google Maps/Android Auto/CarPlay is the future of in-car use. OE navigation is trash.
Forums have taken a hit because of Facebook groups. But, I'm on two groups for 2014-18 GM trucks and they're full of morons. If you want pictures of giant wheels with stretched tires, sign up. If you want real advice, come here. haha
I've read more than one article and a few books about auto design that say when it comes down to it, engineers make design decisions in grams. And yes, they would be considering the full weight as that comes out of payload capacity.
Ford shrank their base gas tank too. The big tank is optional. It is 100% lazy engineering, an easy way to cut weight when they literally go down to the gram when considering part weight cost. People who aren't bothered by it must like having long trips interrupted more often.
I wasn't aware anyone still bothered with this given that basically everyone has a phone with bluetooth. Why pay extra for OnStar calling when you should be able to do the same, assuming you have a smartphone?
1. 15 minutes.
2. Common on a lot of vehicles sadly.
3. Probably a hill-hold feature if you park on an incline? Just guessing.
With the right gearing I don't see why it won't work. Look at old Toyota pickups or something like a Samurai with 2-digit horsepower on 37s or even big stuff like 40s. They run like 5.30 gears though. haha
