I had my concerns about pulling long grades. But after a trip to TN through the NC mountains where I pulled some steep grades for several miles I no longer have those concerns. Sat at 4000-4500 RPM for miles and the temps rose maybe 1-2 degrees. Trans sat at 170F, oil and coolant at around 210. I was impressed. That engine never broke a sweat, kept me at 55 MPH.
The 8spd in your 6.4 is so far superior to the 6spd I have it's laughable. My one complaint (and it's a big one) is the gear spacing in my 66RFE tranny. Mainly, the 1-2 gap is a mile and I get into situations when I'm around 35-40MPH where it can't hold second so, left to do it's own thing, the tranny just slams back and forth between 1 and 2.

This is usually up a fairly steep/winding grade and my 5th is around 11K loaded so I realize I'm kind of maxing out the truck. I'll usually just lock it into first and get up to about 30. It's just too bad because the 6.4 is a beast. I can only dream of how great it feels with the right gearing.

Wow that's a nice payload! My 18 Laramie megacab has a whopping 1648 lbs because of the Cummins. :) Pulls my 33ft TT just fine though. No way I'd stick a 5th wheel behind it.

That's why I love having a payload of 4262 lbs.

I am looking to by a 2022 bighorn 2500 hemi 6.4 that has just over 15k miles which has door label payload 2912#
Or a 2022 limited 2500 diesel with 27k miles and pay load 2200# I Don't plan to pull anything over 8000# They are both great motors though the limited has tons of bells and whistles!! Tough choice as both are great $$ deals and nice trucks

If you're going to bumper-pull (ball in the receiver on the back) then either truck would work well for you. If you plan on doing any gooseneck pulling, you could be okay with either truck depending on how the trailer is loaded. If you're going to pull a fifth wheel RV, you'll have to be careful and do your due diligence to make sure you're going to be okay.

6.4L Hemi will have no problem moving the Cougar 5th wheel. I have a Grand Design 260RD and it is a little heavier than the Cougar and my 6.4 does well getting it around.

Love these towing, oil, filter, tires, and whatever else threads. Brings out all the experts with the "probably" numbers.

Not sure what that is supposed to tell me. Your GAWR Rear is only 4100#, but as a safety margin you also should not exceed 80% of that 4100# so that means your 'real life' max GAWR Rear is ~ 3300# before you deduct your truck's rear end weight and gear. What's left over is your max pin weight.

Looks like you don't know how to read a sticker either:) :rotflmao: :rotflmao::rotflmao::)

You've got a GVW of 6900 lbs, and a RAWR of 4100 lbs. My 'Wagon had more than that on BOTH numbers (I don't recall exactly but I think it was 8900 and 6500?) and I would never put a fifth wheel behind it. Given your tire size, MOST tires available to you aren't going to have the weight rating to pull a fifth wheel either.

I fully understand that nothing any of us say is going to change your mind, but unless you're pulling a Scamp or a VERY small fifth wheel, you're overloaded as soon as you hitch up, forget adding any gear or passengers.

If your RAWR is 4,100... about 50% of that will be the truck itself. So.... you're already down to 2k lbs on the axle before passengers, a hitch, or cargo. Since you have a limited, likely less.

I'm going to estimate that you probably have a 1,400 lb payload or less in the limited since you won't post that sticker.

Unless your fifth wheel is less than 9k lbs, you're over RAWR and payload. Guaranteed. IF you're not, all you have to do is show your payload sticker. Or better yet... a scale ticket. :)

No, you posted it. It's right there in black and white - your GAWR Rear is 4100#. That is the maximum weight your rear axle can carry. GAWR includes the weight of the vehicle, passengers, cargo and trailer tongue weight.
