Promises to be a great power train but the weight of the diesel engine will surely reduce the already limited payload rating in the Nissan 1/2 ton.

Well put. Even stepping up to a 3/4 ton and then choosing diesel over gas cuts into payload significantly, putting payloads almost on par with a half ton gasser.

I know the 5.7 Hemi is a high revving engine vs the low rpm torque curve of the Ford EB, but we have not found any drone or volume issues towing through the Rockies with an aftermarket exhaust and our rear slider window open; it just GOES!
Last summer my wife noted how many downhill grades we encountered on our way to our destination, and we worried all week about the trip home. Halfway home I found just as many downhill grades- we hadn't even noticed all the uphill on our way there.
It really is a great engine, if a bit thirsty.

so if my ties are rated for 65mph why can't I drive that fast? As a mechanical engineer I know about the safety factor built into everything that is designed. Let's just say I don't have any designs that don't have a safety factor applied to then. In in all my years of towing I have never had a tire fail on a trailer camper or enclosed car hauler. At 65mph I am still the slow guy on the road and almost everything is passing me including most other campers.

I use to think the exact same thing...go, go go. Now, through self teaching of slowing down, I really enjoy the traveling and enjoy the ride. I still catch myself going faster than 65 occasionally but with running the cruise control it helps a lot. I do have to pull on the reins frequently as my right foot wants to push till the butt-o-meter is satisfied when manually controlling the throttle. My little V-6 twin turbo'd Ecoboost just hums right along no matter what with its flat curved 420+ lbs of torque.

X2 - when I drove for a living, I would get pretty frustrated by "the old guy in the RV holding up traffic". Now, I'm the "old guy" holding up traffic. I just don't get in a hurry anymore. In response to the engineer that drives fast. As an engineer, you understand the concept of kinetic energy and Newton's law. I know, from bitter experience, that 80,000# traveling at 75 mph will create an unbelievable amount of damage when it encounters a fixed or slower moving object. My advice? Slow down. Enjoy the journey. We're supposed to be having fun. JMHO

Jsmith948, there's also Murphy's Law that will bite you in the rear if you're not careful.

[440justin]

So driving 65mph is considered too fast now? Wow how slow are you all driving on the interstate? I know that I would not feel safe going much shower given how fast everyone else is going. Like the semi's going 75mph! At 65mph they are still flying up my back side and damn near my bumper before they pass! Am am enjoying the drive because if I was not towing I would be going faster.

Aslo have the ecoboost. It is very surprising to see the difference. SOme of the others we camp with have the chevy and dodge 1500 trucks. Not only can I out pull them on the highway I get around 20 mpg unloaded driving. Best money I have ever spent on a truck.

Only because i have the factory info on my desk...

2012 RAM 2500 Crew 4x4 short bed SLT 5.7L V8 Gas (6,285lbs) - GCWR 17,000 - 6,285 = 10,715 load

2012 RAM 2500 Crew 4x4 short bed SLT 6.7L I6 Diesel (7,296) - GCWR 22,000 - 7,295 = 14,705 load

In this case the Diesel option gives you 4,010 more LBS of stuff you can carry...

Payload is generally considered to be the amount of weight the truck can carry on its axles (GVW) if you notice the weight of the gas powered Dodge vs the diesel powered Dodge, you'll see that given the identical GVW, the gas powered truck can carry (payload) almost 1000 pounds more than the diesel truck.

Now, in bold, you'll see the GCWR (maximum pulling capacity) of the diesel is 4010 pounds more. That's related to engine torque (pulling capacity).

The payload (carrying capaicity) for the diesel is about 1000 pounds less and the GCWR (pulling capacity) is 4000 pounds more.

Or to put it another way, the diesel can "carry" 1000 pounds less than the gas truck, (the "PAYLOAD") but can tow (PULL) 4000 pounds more (that's GCWR or COMBINED truck/trailer weight) not to be confused with "PAYLOAD" which is cargo and passengers that's put inside the truck bed/cab and carried by the truck's axles.

You beat me to it.

[audio1der]

Thanks, gents. I also thought this discussion was payload, not pulling load centric.
Seems a stock Ford EB might be the best option?

Very well From the Factory.. again all are for a 2012 RAM 2500 SLT Crew Short Bed

Gas - GVWR 8800 PayLoad 2460
Diesel GVMR 9700 PayLoad 2490

According to the factor the Diesel has 30lbs higher payload. Not sure about fords or GM but when you buy a Ram Diesel the drive train, and suspension are completely different.


Also GCWR doesn not mean how much it can pull... its Gross combined weight rating.. Thats combined weight of Truck, Payload, Trailer.

You are using "semantics" but if it helps you understand the terminology better, that's fine.

In your current example, the diesel payload is 30 lbs higher because the GVW is 900 pounds higher. The remainder of that extra GVW is consumed by the additional weight of the diesel engine. You're correct, the Dodge diesel drive train and suspension are completely different, but the nomenclature and manner of calculating the GVW/GCWR are the same regardless of truck class or type or drivetrain. Payload is simply the GVW minus the truck's weight. What's left over is "payload". "Payload" includes passengers, all cargo, accessories added to the truck as well as the hitch weight of any trailer connected to the truck.

And to clarify your uncertainty, currently, Ford's "standard" 3/4 ton GVW for the Superduty line is 10,000 lb for gas and diesel engines. There is an optional 9,000 GVW available in the 3/4 ton to meet licensing restrictions in some states.

You are mistaken. The GCWR is "specifically what the truck can pull" Every truck has to "pull itself" as well as any "trailer". That's why it's called the "GCombinedWR". Any way you want to phrase it so you understand is a "winner". The PAYLOAD is what's carried IN the truck and the GCWR is what the truck is capable of pulling. If you check my exact quote, you'll see that's what I said. Additionally, the "maximum trailer weight" is the heaviest trailer the truck can pull, and is should not be confused with GCWR.

However, if you want to continue discussing GVW/GCWR as it relates to 2500 series trucks, start another thread, this one is about half ton torque and we are off topic.

Just did a 500 mile trip with my ecoboost pulling the travel trailer. 6300lbs. I averaged 10 mpg and no problem with the hills in northern Michigan.

[SGardiner]

We just completed a 5000 km trip with our F-150 w/ecoboost and Bullet 281bhs (approx 7000 lbs)

I was pleased with the performance. This is the only truck / trailer combo I have ever driven so I have nothing to compare with. I maintained a speed of approx 60 - 65 mph max without issue regardless of the terrain.

The original post here asked which 1/2 Ton has the most torque, according to the latest info from Motor Trend and a couple of other magazines the new Ram 1500 with Eco/Diesel has the best in class and also get the best mileage. It is also rated at 9200 lbs. of towing capacity which by specs puts it ahead of all truck builders.

I do not have one and am only going by what I have read but might be something to check out.

check here....http://www.ford.ca/trucks/f150/specifications/towing/

F150 Max tow and a v6 EcoBoost has a Tow rating of 11,300 lb. That's 2,100 more then the dodge.

Add the max payload package and you get a available payload of up to 3,120 LB.

The New 2015 has even more capabilities but firm specs are not yet released.

tundra mine tows up and down any mountain road, & we live in BC (lots of mountain highways)

sometimes i forget im towing

We just got back from a 1600 mile round trip from STL to Destin FL and back. 5th and 6th gear all the way with no rpms over 2200. Even climbed the "hill" outside of Nashville in 5th. Nice and quiet power with an average of 10.1 mpg round trip at about 65mph on my setup running cruise control (and the AC).
