I would look at the tires, assuming they are stock size. The load capacity x 2 is usually a little bit more weight than the axle rating.
So on my Ram, I have a 7000 lb rear axle and the stock tire apacity is 3640x2 or 7280 lbs of capacity. Tires size is 275/70r18.
Really? Then explain how a 3/4 ton with the same "axle" and same wheels and tires as your truck only gets a 6000-6500lb "axle rating"
That seems like more than a "little bit more weight."
Except a 3/4 ton gets smaller rims and tires.
Before the industry went to 17's, 18's and 20's, standard equipment on a 3/4 ton was 245/75R16. A 1 ton SRW would come with 265/75R16, which had about 450lbs more capacity per tire.
No they don’t. And not talking about OE tire and rim sizes from 20 years ago. Which were also interchangeable. But back to this century,
Each of the big 3 has a multitude of wheel options and they’re basically all available on both 3/4 and 1 ton srw models. Yes some tires are rated heavier , but they are avaiLbe across both model lines.
And if you happen to get one with 17” pizza cutters and which don’t have any heavy tire options, regardless of model, a set of cheap takeoff wheels and tires are readily available.
