Georgetown to Denver Standard brake app

Test was ran using cruise control only for accel and decel situations. Brake applications used only to gain control for curves (if needed), traffic (zero needed) of to retain the lawful speed or speed control set ( 60-65 MPH setting)

Test was 45.2 miles total for both trucks

At zero time, neither truck out of mechanical specs or dangerous.



Ford needed 35 brake applications

Chevy needed 0 brake applications
Results:


Ford won HP
Ford won Torque
Ford won MPG’s

Chevy won Brake attempt
Chevy won hill climb
Chevy won control


End results Chevy is the more stable towing truck, control, grade braking, better ride, engine noise less, cabin quieter

Chevy did more with less and cost to own is less.

Lastly Chevy continued on for a total of 662 miles that day, later returning 9.5 loaded overall 475 miles. 187 miles at 18.8 mpg unloaded.


Ford is at shop with potential engine issue.

    This is the most real test form a guy that knows what he’s talking about both trucks more than capable for 95 percent of truck owners I know
  • @mgatlinmt
    Thanks for taking the time and effort to put these videos together! I, and I’m sure many others, really appreciate it! I’m in the exact scenario where I’m looking for a 3/4 ton gaser and your video series has been super helpful. Thanks again and keep the videos coming!
  • Great video content! By far the most “real work” series that I have seen. I appreciate that you work to keep everything as fair and un biased as possible. These are both common configurations that most folks would see at their local dealers. Keep up the great work!
  • Have not finished this last video yet just wanted to say awesome job and content. I have not been so interested in a short series coming out for years. Really enjoyed all the time and effort you put into these videos.
  • @Featherburner
    Another great video! Lots of info. I'm patiently(not really) waiting for my '24 2500HD LTZ to be built and your testing has given me more faith that I've made the correct purchase. Thanks!
  • I really appreciate your insight and thoroughness on this test. I have always tried to keep an open mind when I came to my tow vehicle for our RV. When we started RV travel we had 1 child and my first tow vehicle was a lifted 2 door Tahoe, what an idiot I was. We then gravitated toward a 3/4 ton Suburban as the family grew and loved it. As our RV outgrew the capabilities of that Suburban we eventually had to make a decision on what to do, buy a diesel Ford Excursion or Swap a Duramax and Allison in to our Suburban, the Ford rode so bad that we went the swap route with zero regrets. With the wife, 3 kids and 2 dogs it was very comfortable and towed like dream. So I quickly became a GM guy. When it came time to finally switch to a truck in 2020 as the kids aged out I looked at them all. RAM (terrible payload numbers in the 2500), Ford (still rode like crap) and Chevy/GMC (just right). Even though the GM just never got any love from the testers on YouTube, RAM and Ford always won in their tests, I was scratching my head. I keep saying, this truck performs great, why do they always pick a truck that either rides terrible or has such low payload numbers it barely would qualify as an HD. Is the interior design really that important to the performance of an HD truck.. So thank you for the honest assessment. And as far as gas goes, their is a reason why the GM V8 is great, from the venerable 350 to the ground breaking LS, GM gas engines have always performed, and now that it has a 10 speed behind it, its going to do well. Keep it up, I have subscribed.
  • @Billybob50119
    This was an awesome well thought out test! Best I have ever seen! Awesome job!
  • As an engineer, I appreciate all of the spec detail you provide. Thank you. Please consider that when doing a series of videos to put the links in order in the video details or in the top of the comments. It will make watching the series in order a bit easier.
  • @flamarlamb
    Thanks for the good honest real comparison. I have a 2020 F250/7.3/3.55 CC SB 4x4. 38k and no noteworthy issues. I tow a 7600 lb travel trailer mostly around where I live, GA and the southeast. I’ve pulled to Denver once and to San Diego via I-40 down to I-8 once. Both trips averaged 9.5 mpg for the entire distance out and back. I used 87 octane mostly but premium when I got to the mountains, it did make a difference. Like you, I tend to keep my ascent and descent on steep grades slower. It’s good to hear that confirmation from a pro driver. I haven’t had any issues yet except what I would call an unusual buzz/vibration when the truck downshifted to 3rd coming down the last steep descent on I-8 into San Diego. Speed was about 55mph if I remember. Never had it happen before and only a time or two since, in 3rd only while engine braking.
  • @tomchepey2999
    Absolutely fantastic series of videos. Excellent detailed comparison with such analytical thought. 👍🏻👍🏻. We bought 2020 F350 with 7.3 and 4:30 axel Still love it with no problems at 40K miles. Duratrac tires wearing even and not no
  • @bryaninnc5511
    I came across your channel just as you started this series and held off commenting until I watched the last video. Your content is a refreshing change from those “other” channels. Nothing irks me more than some guy giving a review of a high trim truck that every other channel is reviewing. I would never buy one so all the over priced features don’t interest me. I currently tow a 7K travel trailer with my F-150 XLT long bed with the HDP and max tow packages. This video was a good, honest review of both trucks and I would seriously consider either of them once my wife and I retire and hit the road more frequently.
  • @tonycorsi7988
    Thank you, Fantastic series on the gas powered trucks. I have a 09 Duramax that I got new, it runs good but now with a fifth wheel I need a larger payload. Very seriously thinking of one of the new Gas trucks, you provided very good information in a real life setting. Keep up the good work.
  • @cheekster96
    OUTSTANDING series! Great comparisons ! Go Big Red!
  • Great head-to-head comparison. I just bought a 2024 Silverado 2500 LT. I will be hauling my camper, which is about 9k lbs, up and down the hills of WV and MD later this week. It makes more sense to compare trucks hauling the exact same load instead of maxing the load to the trucks individual towing capacity, which could vary by thousands of pounds.
  • @TheOMEGANOX
    Thank you for undertaking this mission, despite the distractions it was a roaring success, and put a lot of fairytales to bed with facts. I'm going GMC but this will be my first chevy truck after a lifetime of ford. Could not have arrived there without your work.
  • @T.Z89
    Awesome series keep it up!
  • @samduran5180
    Thank you for the honest review! I'm now going to purchase the 2500HD GM no doubt.
