Good to see some Ike Gauntlet pulls again and no surprise the Ram performed better than the Chevy in braking performance and fuel economy.

Thanks for posting this!

They also liked the ride better on the RAM with rear coil springs and solid front axle.

So you people that insist RAM should go to a 8-10 speed trans what say you now?????? Big difference in fuel economy.

Sad they did not hook some real weight to the trucks.

My take is with this small camper the 6 speed/Cummins combo was a good fit. Go to 30k lbs and I believe you'll see a different outcome or different varying size slopes/hills.

it looked like the chev wasn't on tow mode from how they figured where it was located. Might not be different but it is on our 05??? Fun to watch. chevman

RAM sure seemed to win except for payload…2234 vs. over 3000…but hard to pull 20000 pounds with RAM’s small payload.

The main issue with the Chevy is it didn't downshift until a brake application and then the rpms went up to ~2,500 rpm's like the Ram and it held the speed thereafter.

Ya, you’re right. Maybe the 68rfe is the best trans offered for the last 15 years. LOL

YES let's see the big three with their DRW trucks towing 30k up and down. RAM should have the 4.10, GM only has 3.73 and not sure what Ford offers. Mileage and control of the load will go to the RAM. Ford will probably be faster than RAM but who knows.

The inline 6 does JUST FINE with the 6 speed. Higher revving V8 diesels may do better with more gears. I tow more weight than most anyone on here and West coast to boot. I see ZERO benefit to my heavy towing having any more gears.

I have tried AUTO mode and with my weight it's NO BUENO! I use cruise control with Max EB and hold 6% and much more with ZERO brake applications.

didn't the exhaust brake on the chev slowed down more than the driver wanted?

plus the chev was a 3.43 Rear diff. Nice tow with either truck. chevman
