When a Denali can have bench seating in the front, cloth & not leather (vegan) then I'll buy it but until then I''ll just keep the RAM dually 3500 tradesman. Porsche, Mercedes and Audi which I know are cars offer Vegan seating, everyone else should follow suit too.

Now do it all for a reasonable price.
Cars and trucks are getting out of hand with how much they cost. People are getting sick of these prices and you'll be sorry you didn't change your ways

Not a fan of the 17” tires. Too small for the wheel wells. They don’t look right. They’re not to scale for the size of the truck.

I saw one of these in the flesh not long ago and in black too! Umm, maybe it is the same truck doing a commercial in my neighborhood.

I have the SRW 3500 and I wish there was a display to show what gear you’re in.

It would be great, if the big three would make the DEF filler neck, accept the normal truck stop DEF filler nozzle at your typical diesel fuel island. No more plastic jugs!

[shorttrackthing]

This is my dream race hauler, I want to get this in the oem bronze color

[tiny_kyd]

No electronic cooling fan??? Need to turn on the entire engine wasting fuel??

[chhailykung]

Dear Ford motor company, if you want to sell more trucks, you need to have an additional option for the "crew cab." Basically, you need to have a factory built (toilet) that fits in the crew cab. The "cruse cab" will have the same doors (maybe no window), or just one door.
If you do not think that I am serious, consider the fact that the camping ground will only be open for vehicles that have toilets. I do not want a van or anything bigger, I want a pickup truck that has a toilet built in. The company that delivers that truck will thrive during and after the Coronavirus pandemic. I will send the same message to the competition. If you get it done, I will buy the cheapest model or will accept a donation of a fancier model. Good luck!

Sticking with my '01 LB7; no egr, no dpf, no def from the factory. Emissions garbage is killing new diesels, and now they're more expensive than ever to delete. Guy I work with said it was $10k to delete his '20 dmax. You guys can keep all that.

Lol. Lot of this isn’t new GM inventions. I have 2 stage exhaust brakes on my ram which out classes GMs and Fords in proven tests. Also not 910# torque to the ground (off the crank). Ford and Ram have 1060 and 1000 foot pounds torque so GM is number last place. Heavy Duty coolant fan 😂 they’ve all done that for 2 decades. Cool down idle, yep they all got that.

All in all, these are beautiful trucks with remarkable performance but they’re certainly not exclusive in rank.

BTW. GM had the agreed upon standards lowered so that they could out gun Ram and Ford but now that they are all tested the same again, they are in last place😂😂😂
