RE: 2020 GMC
Let’s not forget 700# lighter and 50% less tire drag.
I would like to see the math you used to calculate the tire drag.
Especially without having the drag coefficient of the asphalt. At least I assume he hasn't run a drag box across the Ike. But maybe...
FYI comprehension of what you have read is important. Dually has 6 tires and SRW has 4 that is 50% less "tire drag". We good now?
When I went to school, 50% of 6 was 3. 33.3% of 6 is 4.
Well, 6 is 50% more than 4. So I guess he meant that the RAM had 50% MORE drag than the Chevy, not the other way around. But I don't think that equates to a 50% increase in drag. Maybe I'm wrong.....

RE: 2020 GMC
3. 10 speed Allison
3. GM 10 speed re-branded as an Allison.
Fixed that for you.
And Gig'em Aggies.
Aren't the GM and Ford 10 speed transmissions very similar...believe both companies shared R+D on that.
That’s on the lighter duty transmissions. Shared between the two - the F150 uses it along with the F body GM cars.
This one is different.

RE: GM Yukon XL Denali Transmission Temps
Paying more attention to temps now. After the install of the new aux unit on the Yukon i drove 40 miles on the interstate on Monday morning. It was cooler ambient probably 70. Yukon trans temp gauge showed a high of 127.
Rented a new Traverse in Nebraska. On the way from Lincoln to Omaha I saw this type of temp. 90* ambient.
Chevys must just run hot. ?

RE: New Ram/Cummins vs GM/Duramax on the IKE
With the 60MPH limit for this test.... That was the biggest factor in the outcome. Both trucks were pretty much at the limit the whole way up the hill. With both trucks able to do that, there were very few areas where one could assert an advantage.
Though I would have liked to see a couple of DRWs go at it, I doubt the result would have changed much. With a 16k trailer and a 60 MPH limit... Neither truck will be pushed enough to make a difference.
What I saw, and what they said was that both trucks were only able to get to 56-58 mph flat out on at least some sections.
Which honestly still seems high to me. I tow that stretch several times per year. Did it 3 weeks ago with my 12k fiver and my 3k(?) Boat. My truck was between 40-45 most of the way up. I think that the higher profile of the RV must make a huge difference as I have a friend with a 2013 Ford and he is about the same speed.
As a side note, the speeds are about the same regardless if I tow the boat or not.

RE: 2020 GMC
The 8 speed ZF in my Grand Cherokee is far and away the best automatic I’ve driven. I’d love to see one in RAM.
I’m sure there is a point of dimensioning returns on more gears in a vehicle. Not sure if that is 8 speeds or 10 or more. But I would be shocked if 8 wasn’t better than 6. And I’m sure that 10 is better than 6. My 68RFE could use one more gear above 6 and probably one either between 3-4 or 4-5.
GM has this right in theory. We will see how it plays out in real life.

RE: Should I tow my Grand Cherokee or get something lighter?
Even if you went down to something WAY lighter, I really don’t think you would see appreciable difference in the towing manners of your rig. Keep the GC and use it as your towed vehicle.

RE: GM Yukon XL Denali Transmission Temps
Installed the TruCool today. I am curious if anyone that has experience with this unit, and has installed it on a GM SUV or truck, did your outside temp gauge still work after install?
The reason I ask is that mine doesn't. And from looking, the sensor is right in front of the radiator, looks like it may now be blocked by the TruCool. And if it isn't blocked, it sure is a lot closer to it than it was to the OEM cooler.
Cheap part to install, and it doesn't look like it would be a terrible installation, just want to know others experience before I go chasing down a rabbit hole if it is a lost cause.

RE: New Ram/Cummins vs GM/Duramax on the IKE
This conversation should be about the Duramax L5P and the current cummins with the CP4 and reduced compression. I'm hearing reports that the latest cummins is making less fuel mileage than the previous generation and maybe requiring more turbo boost now to make equivalent power.
Can you please post any links where you have been hearing these reports? I would love to read them because some new Cummins owners like Lavon Miller at Firepunk diesel has been doing video blogs about his new 2019 Cummins he just bought with dyno and others tests comparing it to his 2017 stating otherwise.
Also, reduced compression is likely due to the increase in fuel pressure coming from the CP4.
No official links but my cousin mentioned that the service department has received several complaints on fuel economy on the '19 trucks are noticeably lower when either pulling or running empty. Also I spoke with a hot shotter who I know that handles a lot of our material handling between our sites reported lower fuel economy compared to his 4 gen. It maybe a bit too early but it sounds like something is going on.

RE: G.M.'s in line 3.0 diesel video.
If in fact most engines are designed with that 150k target, the GM engineer really botched his answer. And Mr Truck made WAY too much out of the rating.

RE: G.M.'s in line 3.0 diesel video.
Pretty much all vehicles under 8,500 pounds are validated to 150,000 miles.
What's different here is that major components (oil pump belt mainly) will need service at that point, and it does not appear easy to get to. Timing chains rarely fail without warning, so you can just keep on running them until you start getting telltale timing chain slap or valve clatter.
Just because an engine is "only" validated to 150,000 miles does not mean it can't last much, much longer.
I'm interested in this. It isn't that I don't trust you, but where do you find documentation that all vehicles under 8500 pounds are validated to 150k miles? Is that the "medium duty" spec comes in?

RE: G.M.'s in line 3.0 diesel video.
About 8.5 minutes in they state the 150,000 engine life, and they say "same as the Ford". Which Ford are they talking about? The new 3.0?

RE: 1/2 Ton Towable 5th Wheel
Actually I did just that in March. Depending on incentives in effect, the price is within a couple thousand dollars of each other. However, at least in March, the incentives for the F150 were $8500 more (cheaper) than the F250. And besides that, I have the 3.5 ecoboost and a 10 sp transmission, a combination that is far and away superior (in my opinion); And especially so if you are using it as a daily driver. I dumped my V10 F250 and couldn't be happier.
You have a much more reasonable approach - with the truck being a daily driver. OP is asking about a dedicated tow vehicle that he will full time in.
F250/2500 is a better choice, even if it is a little more.

RE: 1/2 Ton Towable 5th Wheel
There really isn't that much of a cost difference between a 150/1500 truck and a 250/2500 truck. You might need to check a few (not many) less option boxes on the 250/2500, but you get a lot more truck that is better suited for towing.
If you don't have the truck yet, investigate further. You will open up many more options for a RV, and have a much more pleasant towing experience.
That said, when I eventually retire, I will almost certainly sell my 5er/truck, and move to a motorhome. About the same amount of tires to replace, not much more maintenance on one more engine, and, in my opinion, a better platform for full timing.

RE: hitch weight rating
I don't know why, but I have never seen a hitch rating sticker on RAMs. I know my 2012 doesn't have one, and it has prevented the local rental store for renting me a trailer due to their insurance policy.
Will be following to see what you find out. I am sure the rating is out there somewhere (although I don't think you should go by the door sticker for the hitch rating).
My 2013 has the specs molded right into the rubber step on the bumper
I am almost positive that those specs are for using the bumper hitch, not the receiver hitch.
