Toyota Tundra payload issues?

I looked on the door jam of a 2016 Silverado and didnt see anything about payload.

The wifes 2016 1500 crew cab chevy 4x4 payload sticker which is actually a yellow tire placard sticker and its is located at the bottom of the drivers door opening per fed regulations. The placard on her truck is 1640 lbs.
Her truck has 4000 rawr which equates to around the same 1600-1650 lbs before exceeding a wheel/tire or rear spring pack.

If you choose to stick with a 1/2 ton truck you need to do your homework on which trucks have the highest RAWR numbers.
"SOME" new gen 1/2 ton trucks with a high gvwr numbers are overloading "SOME" trucks rear axle/tires with those small 3800-4100 lb RAWR.

Check out the newer GM 1500 trucks with the NHT package. This package is a 7600 gvwr and 4600 rawr numbers and is good for around 2000 lb actual payloads in the bed before exceeding rear axle tires and wheels or rear suspension..

And Fords F150HD at 7750 gvwr and bigger 4800 rawr. This truck is good for around 2200-2400 lb payload in the bed before exceeding the rear axle tires or wheels or rear suspension.

A regular cab long bed 2wd will have more payload in the bed vs a 4x4 crew cab long bed truck.

Be more realistic and choose a truck that can carry a loaded (wet) truck camper...not its dry weight.

You can add whatever you need to level the trucks rear but I would not carry more weight in the bed of a 1/2 ton truck than its axle load ratings. 1/2 ton trucks use a semi float type axle = one small bearing at the end of the axle. They do not like to be ran over loaded and can fail sooner than later from doing so.
Yeah I've done it in my younger and dumber days. :B
