Need help!!!

My husband & I currently have a 07 Tundra & a 29ft TT. We're upgrading the camper to a 5ver, 2014 Coachman Chaparral Lite 279BHS, YAY!! But upgrading the camper also means upgrading the truck. We're leaning towards a 2014 Dodge Ram 2500 5.7L V8. He's crunched all the numbers & he knows that this truck will tow the camper but we wanted to see if anyone out there has the same setup or something similar. Does it tow good? He doesn't want to go buy the truck to only find out it lacks in towing. Any info/advise is appreciated! THX in advance & HAPPY CAMPING!

I have a 2012 ram mega cab 2500 4x4 with 5.7 litre hemi. I have a motor home so I do not tow a camper but I'm a contractor and pull 24' gooseneck with 9000# backhoe and 14' gooseneck dump trailer. When I pick up sand I weigh about 24,500# loaded. This is first gas truck I've had in years. I've had Cummins diesel trucks since 90's. I am impressed with how it pulls. Mine has 4.10 rear end and that helps. My fuel mileage is pretty fair for what I do. Especially when u consider diesel cost about $.50/gallon more and additional cost of diesel engine. Good luck on your decision. I think you would be happy with it.

Chad

I'd go 6.4 way before the 5.7. Better mpg not towing with the 6.4. Also get the 4.10 gears in either. I have a 12 Ram 2500 CTD 3.73 and tow a 9000lbs 5'er. No way would I want a 5.7 for the 279BHS. It'll be around 10,000lbs+ loaded. You have kids I'm guessing since you're getting a bunk model. So you could hit 10,500lbs on the 5'er. If you have any kind of mtns then that 5.7 will be working hard. The 2500 weighs 13-1400 more than the 1500 so that needs to be factored in. IMO the 5.7 is good for 7-8000lbs max. It's a great motor for the 1500 but the 6.4 is a much better towing motor.
The 6.4 has cylinder deactivation also which helps when running empty on the hwy.

There are two weights to be concerned with when matching trailer to tow vehicle.

1] the max combined weight the drivetrain can pull over hill and dale without overheating anything in the drivetrain, and without being the slowpoke up hill or pass holding up traffic.


The 2014 Ram 2500 with 6.4L Hemi engine and 4.10 axle has a tow rating of 12,297. A more realistic tow rating is around 11,000 pounds. And guess what, your bunkhouse will probably gross between 10,000 and 11,000 pounds when wet and loaded on the road. So that's a good match for the pulling power of the Ram 6.4L Hemi.

2] the max payload the truck can haul without overloading the suspension of the tow vehicle.

The 279BHS has a dry hitch weight of around 23% of dry gross weight. So count on the wet and loaded bunkhouse having over 20% hitch weight (pin weight). 20% of 11,000 pounds is 2,200 pounds. So when weighed with all the people and stuff that will be in the truck when towing, including 5er hitch, the truck weight when subtracted from the GVWR of the truck should show at least 2,200 pounds of payload capacity available for pin weight.

That's bad news for you. A regular cab Ram with SLT trim has max available payload of less than 3,000 pounds. Add a CrewCab body and 4x4 drivetrain and you'll be right up against the GVWR of the pickup before you load anybody in the truck. if you can convince Hubby to buy a 4x2 instead of a 4x4, then you can probably haul the family in the truck without being overloaded. But no tools, campfire wood or anything heavy. Everything has to go in the trailer, not in the truck.

So in a nutshell, that Ram with 6.4L Hemi engine can pull the trailer with no big problems, but it probably cannot haul the hitch weight of that trailer without exceeding the GVWR of the truck.

A 14 Ram 2500 6.4 Hemi 4.10 CCSB 4x4 has a max tow of 15,500. Payload of 3170lbs. Rams web site payload ratings are really close to what the truck is delivered.

Even maxing out the GVWR of the 5'er and using the standard 20% pin weight you'd be around 2200lbs on the pin leaving you 900lbs for passengers. They'd be close but doable IMO. Most weekenders don't load 2330lbs of gear in though. 1200-1500lbs is more reasonable.

But what does it get when you connect that big trailer?

Here's a report on a guy towing 11,000lb 5'er with a 2014 Ram 6.4 with 4.10

I think if you do purchase the 5.7L, you'll constantly be driving it and anytime it struggles, you'll be thinking, "man, should have gotten the 6.4L".

The hemi 5.7l is similar to your tundra's 5.7L engine. So just imagine using that to tow that much weight, plut another 2000lbs of truck frame. It's alot for that engine.

Those 2 engines are Quite different. All of the Hemis are 2 valve engines but are more efficient for the power they produce.
The Toyota is a 4 valve(per cylinder) engine and as such is tuned for a higher RPM.
The 5.7L Hemi have been on Wards 10 best engine list 3 times (03-07 & 09)
Toyota hasn't had a engine on the list since 2001.

I don't know about that. In terms of output, they are very much the same.

Tundra 07: 381 hp @ 5600 rpm , 401 ft-lbs. @ 3600 rpm

2014 Hemi 5.7L: 383 hp @ 5600 rpm, 400 ft-lbs. @ 4000 rpm

2014 Hemi 6.4L: 410 hp @ 5600 rpm, 429 ft-lbs. @ 4000 rpm

But what's not shown here is that the 6.4L was designed to work harder. More oil cooling features like piston oil jets, and larger oil radiator etc.... It was also designed for more low end grunt, to take advantage of cylinder deactivation for longer periods of time.

13MPG towing 7200. The more I break in the engine the better it has been.

Looking at the figures above, I am not sure why you would add 2K # and trade up for 29 hp and 28 # ft of torque. I just bit the bullet and bought a Ram 2500 with the 6.7 diesel. I'm currently paying about .15 more for diesel than regular unleaded, and getting better mileage on average by 2 mpg. I hate to join the "Buy the Diesel" crowd, but, I guess I'm there... Sorry.
