I highly advise listening to Jerry on this one!!!

Difference in a 3/4 ton gas truck empty rear axle weight vs same same 3/4 ton diesel can be from 80 lbs to around 200 lbs depending on brand/year model.

And depending on 3/4 ton year model RAWR can run from 6000-6500 lbs.

GM has a weights calculator that will tell you each trucks axle and gross weights of each selected cab/engine/drivetrain standards and options. https://www.gmfleetorderguide.com/
Just follow information required. This will get you close to most similar equipped other brand 3/4 ton trucks weight specs.

A ball park pin weight number requires you to tell us the trucks year model/cab selection/engine/manual vs auto tranny/4wd vs 2wd/gvwr/rawr.

I don’t believe this is even close to accurate. The only weight you need to look at is on the drivers door jam. That payload weight takes into account brakes, tires and other options. The weight rating of the rear axle is not the limiting factor.

More information as re year model etc the 6.2 gas can carry Bout 800 lb more than diesel.

I think those trucks generally run in the 6200-6500 lbs range for RAWR. Subtract your empty rear axle weight from the RAWR and that's the number. You can play with it a little bit depending on the particular truck. I wouldn't have any qualms taking my Ram up to the 7000 lb RAWR on the equivalent SRW 3500 because I think the Timbrens I installed more than make up for the 500 lb lower rating due to the different rear suspension setup. Others might have a different take and that's fine.

Obviously you need to account for stuff in the truck, too - people, cargo, hitch, etc.

For those people who have either truck, what would be the max 5th wheel pin weight you would feel safe with? I have been researching but I'm getting conflicting reports online. I figured I would go right to the source.

Thanks,

If you are just now buying a truck and intend to tow a 5th wheel, I would recommend you get a 350/3500 especially if you are planning on a diesel. The price difference is just not that great.
If you already have the truck, then look at the door sticker. It will tell you the payload, then you can figure out the maximum pin weight.
Figure 25% of the fifth wheel weight will be on the pin.

On a new one (2014) and up I'd be okay with 2600-2800 lbs on the rear axle. However you play the numbers thats the total. Pin + 5th hitch + gear in the truck bed.

I'd be fine right up to their ratings. I don't think there's any reason not to trust those.

Don’t know about the Ram. But the F250 payload varies a lot depending on truck configuration including wheelbase, options, and even tires (17”/18”/20”, with 20” offering greater payload).
