I think what
@Grand Mesa means is that 3/4 ton is 1500 pounds. The Base Tradesman with Powerwagon package for 2019+ can have 1620lbs...so more than 3/4 ton capable lol.
The CAT scales do have a +/- 20 pound leeway per pad. So you could be 40 pounds off...which gets the number close.
But I for sure would guess with adding stuff it should weigh more...not less.
GVWR 8565 minus 1565 payload means the base weight should be 7000lbs. So you are 50 pounds off...did you change wheels also? Could be your tire and wheel package saved you some weight,
@retired
For reference, my Tradesman Crew 8' bed with only protection group and tow mirrors as the only option weighs 7002lbs.
And the chart lists a Tradesman with Powerwagon Package having a max payload of 1620. Of course you can option the tradesman up to weigh more than a base Powerwagon trim.
But 1620 would be the most and I have seen door stickers as low as 1065.
The 2 heaviest options would be RamBox and sunroof.
