Usually a half ton runs out of payload before it hits the tow rating. Also keep in mind these charts for payload and tow rating are best case, often adding options to the truck reduces those numbers.

So from the info on the above chart I am assuming the OP is putting a bit of strain on the transmission and / or rear end ? Rest of truck would be the same regardless of the ration on the rear end I am guessing.


I'd be more worried about stopping the load.


More what I was wondering is if the breaks, frame, u-joints, any different on the same model truck with a different rear end ratio ?

My 10,170 is based on VIN from RAM. Note that it's 40# less than the Max in the chart. My guess is the 4-corner air suspension.

My 2015 RAM 1500 SPORT QUAD CAB 4X4 6'4" BOX is rated to haul 10,170.

Grossing that maybe. Hauling definitely not.

Well, you guys have got me checking my owners manual to see what chevrolet recommends and I guess I am exceeding their limits. They list 9,900 # max trailer weight for my truck and a GCWR of 16,000# since it has a 3.73 rear axle. But they list the same truck with 4.11 gears at 12,400# max trailer weight and a GCWR of 18,500#. Both trucks are identical with the same OEM 2.5 inch tow hitch. i have a 7X12 12,000# dump trailer that I use for hauling stone from the quarry. The tare weight runs between 10,400 and 10,500. I always ask for 5 ton and usually gross about 21,000 +. A load that size handles nice, stops good and just feels right. My truck has a transmission oil temperature gage that I moniter when towing. It never exceeds 165F and normally runs at 145F. It only creeps up when going up a couple of the long hills that I travel. Of course most of my driving is flat land. If I was traveling in high altitude and real long grades I would surely be overheating something. I watch all my temperatures and speed.

I did come out of the quarry once with 7.1 ton of stone and a gross weight of 24,700. That load really felt heavy and I never went over 45. It was only a 20 mile trip and I kept watching my tires in the mirror all the way home. I was sure it would not dump but it did OK. Not without a lot of creaking and groaning though. Looking at some of my quarry tickets I would say that a gross weight of 21,000 to 21,500 is kind of a comfortable gross weight for flat lands that I travel. I guess I will keep on doing what I have been. Everything seems to be working fine.

What’s the road out of the quarry you load at like? The quarry I load at is pretty steep. It makes me kinda nervous pulling out with trucks. I’d hate to do it with a trailer.

I've mentioned this in the past, I stopped into a coworker's house a few years ago just after he pulled in with a 14k tandem axle dump behind his company 1/2 Silverado loaded with 8100 lbs of stone... and no trailer brakes. Total weight including the trailer was around 6 tons. He said that he had driven right through town with it. :eek:

The road out of my closest quarry is also a steep climb out. Plenty wide enough though for two way traffic. The day that I got loaded with the 7.1 tons of stone it was raining pretty hard and I had to put it in 4-wheel drive climbing out of the pit. I thought about shoveling some off but with the rain decided to just go slow. I had requested 5 ton as usual but that time the payload driver way over did it. I'm pretty sure they have a scale of some sort on their machine that indicates how much stone is in their bucket. I ws really surprised when I got my scale ticket.
