Tow Vehicle for 22,000 Pounds Plus

[Texas_Roadrunn1]

Is anyone towing 22,000 lbs. plus? If so, what are you towing with? Which rear end, what kind of mileage do you get? Do you have any tips? Have you pulled in the mountains, any problems? Thanks so very much for your help.

The RV has a GVWR of 21k. It actually weighs 23k. The axles weigh 17,500#. The tires are GY "H" that rate at 4,806# per tire. I will be at MorRyde in May to add the 2" riser so that will transfer some weight to the truck. May possible upgrade the IS suspensions at that time.

I hope your numbers are backwards. Towing 2k over GVWR is not smart.

No they are not backwards. I could swap out the 21K TrailAire Kingpin to a 23K MorRyde Kingpin and all would be well. But I did replace all the 5/8" bolts holding the kingpin to the frame with 3/4" frame bolts. I am 750# over the 8K axle ratings and as said may upgrade something at MorRyde. Also my tires are more than strong enough.

The correct truck is the truck the spec's say you can pull with no matter what the brand or size.

Ford here. It's a great truck, don't let the haters fool you. They have no issues I run a fleet of trucks at work. Total of a million miles a year. No problems to speak of.

30k total on the scales. Ram owners brag torque and forget hp. Fact is any mordern drw has more than enough power and capability to tow a 20k plus trailer.

Watch fast line truck videos towing up I70 see what truck pulls it fastest if that's important to you. Then see how close that all are. Smh

Not into fast...Street light to street light isn't what I'm going for now., nor are any Ram truck owners, WE KNOW, which trucks are FASTER..Longevity and reliability while towing heavy in the mountains is what I'm looking for...If I wanted fast, I'd opt for the Chevy D/A...or the Hellcat:B

Didn't see anyone hating in here except for the OP, up to his usual...Appears topic was about Chevrolet ....how did Ford get in there? I owned 4 of those D/A combo's they were great, still are, I'm just open minded enough after 35 years with Chevy, so try another brand...and I was fortunate to pick another good one..Hech, all of the Big three are good, but if someone can't start a fight about whose bike is the fastest or the best, this wouldn't be an elementary schools play ground and we couldn't be little boys playing with the usual dose of "bully" thrown in....today's new cyber world...Walk tall and carry a big keyboard:B

I tow a combined weight of 32,500#, 23K of that is the 2016 39TKSB3 MobileSuites. I am within all SAE axle and tow ratings. TV front axle 5,460# rear axle 9,580#.

Truck is rated at 6K front axle, 9,750# rear axle and combined at 37,800#.

NO you don't need a MDT or HDT to tow this size RV. I have towed the whole West Coast with zero issues including high winds.

Truck is a 15 RAM Dually LongHorn with 4,10's and Aisin transmission. I averaged 8.65 from WA to CA with two of those tanks having severe head winds. Without the two bad tanks I would have averaged 9mpg. IMHO that is good mileage for that weight. Some will claim more but that is taking tanks from 7.5 to 10.5 and averaging them all out.

The exhaust brake is AWESOME! Lock the trans in the same gear you would have climbed that grade in and set cruise and enjoy the ride down!

The factory rear air is awesome, the truck rides great loaded and unloaded and also sits the same with 9,580# sitting on the rear or empty.

It has that much GVWR with just 2 #8000 axles??

GVWR is 14,000#..FAWR is 6000#, RAWR is a conservative 9750# ( thats 15,750#), with all 4 rear tires aired to 65 psi...per AAM, you could actually air all 4rear tires to 80 psi , (max sidewall psi and easily take RAWR to 10,000# plus...AAM rates 11.8 axle at 11,500# RAWR. with tires that can cover that weight.

GCWR is different, depending on trannies and gearing, with Aisin/4.10 giving highest TQ and GCWR..2016 Longhorn, crew cab, longed, 4X4, Aisin with 4.10 is 39,100#

You sure do have a purty truck and 5er there Ron:B

I have the 3.73's in my truck and I do like them but if I was doing it again I would probably get 4.10's. I just find it wants to go a little too fast on the highway when pulling, like 110-115 km/h. Drives nice there, feels great power wise, but it's not great on fuel and a little faster than I would prefer to tow 18000ish pounds.

[sayoung]

I. Don't have that heavy a 5er BUT have used my 2012 Chevy to pull my 30ft gooseneck flatbed close to 28000 lbs several times before retireing in Dec. I had no problems that ever made me think was unsafe or undo able for my 3500HD crew cab.
2012 was rated for a 23000 lb 5er & the newer I seem to recall 23300 lbs.
The duallys are all capable so it just boils down to what you want to spend your money on. I had a customer last year that bought a "big rig" Peterbilt and converted it to single axle,custom bed,hitch,& the stove/fridge required here in Texas to register as MH for right at $20k but he has a shop & pretty handy.Its just what you think is "cool".

Not if you're locked in 5th when towing, which by your own admission you are.

When you look on here Ram Bodybuilder Clicky, a Ram DRW Crew Cab with Aisin and 3.73 gear has a GCVWR of 33,800# and a Max trailer weight of 25,010 #. Now I didn't go to all the big name schools but simple math says that truck will have ZERO problems handling a 22,000# camper. Yes the truck with the 4.10 has even more capacity but so does a HDT/MDT.

Yes, it's sufficient per the ratings, but some of us prefer more operating margin when towing as heavy as the OP states. That's what the 4.10s offer.

I have test driven brand new trucks set up exactly the same right down to the radios back to back running the exact same routes with the two gear ratios we are talking about and when you figure I personally saw 2 MPG difference (14-16) I'm not going to be easily persuaded to think otherwise.

Fuel consumption when towing is far more complex than being directly proportional to final drive ratio. To predict whether a particular axle ratio would have better or worse fuel economy at a given speed, one would have to have access to a full brake specific fuel consumption (bsfc) map for the engine across its full speed and load spectrum. Optimum bsfc is often lower in the engine's RPM range than the torque peak (also the bmep peak) or horsepower peak.

In theory, pulling the same trailer, your truck locked in 5th gear should get the same steady state fuel economy as a 4.10 truck in 6th gear as the overall effective gear ratios for both trucks are the same as evidenced by the 1750 RPM engine speed @ 65 MPH.

I don't think we are talking modified trucks here. 900TQ is not stock for your truck. I can't remember do you have 68RFE or Aisin?

No, don't worry. You have the most torque. My truck is the 850TQ and yes it has the Aisin. I just know that my 20,000# load is no problem for my 850 left with 3.42's so I know that 23,000 is not going to be a problem for 900 lbft with 3.73.

His truck has the 865 TQ, the 2016 has the 900 TQ numbers, if not mistaken.

If you are planning on drag racing get the 4.10 if not the 3.73 will be more than enough gear an better all around gear.

If pulling a 23,000# 5er 4.10's are nice to get rolling, and hills.

Like I said before, I pull with 3.42's and yes there is a difference but I have never had an issue " getting going ". I have actually had my traction control kick in a couple times on damp roads taking off at lights that are on hills. Be leave me, 900 lbft of torque has no problem getting 23000 moving or keeping it moving.

Which is precisely my point. When towing, you effectively don't have a 6 speed transmission. You have a 5 speed transmission with a taller 1st gear as compared to a truck with 4.10s. If you like to operate that way, that's fine - your money and your choice. Is the truck capacity optimized operating that way? No.

There's a reason why Ram GCWR ratings increase so markedly as axle ratios step from 3.42 to 3.73 to 4.10.

Rusty

First off, I do have an effective 6 speed. My truck will not shift into 6th until you hit 65 mph in tow haul mode. When running 68 or so it does lug a little more than I would like. I am not the one here that is asking the question about gears. I know what I have and what they are capable of and I also know the exact reason why I have these gears. I do not want or need a DRW truck so unless I buy another brand of truck I'm stuck with the 3.42's. I will just change the diff, oil more because I know it creates more heat.

As far as what I'm saying about the 3.73. I am just assuming here but I was thinking that the OP is looking at DRW trucks here.

I just changed the gears in my F350 from 4.11-3.73 today so I will definitely be able to see what the difference is. I have just over 200,000 miles on the truck with the 4.11's so I am curious to see the difference.
