Trying to understand payload

You are correct except for the gas. Payload will usually include full fluids. You could load the truck up with everything you plan to take, fill the tank etc and go to a scale. Subtract the scale weight from your GVWR (should be 7200lbs for that year Tundra) and you'll have the exact weight for payload left over.

Be careful with hitch weight numbers too. Make sure you don't use "dry" or brochure weights as they are for an unloaded trailer and don't include options, propane, batteries etc which all increase the tongue weight. If you can't get an actual hitch weight when loaded then you should estimate the trailers weight and take 12-15% of that for tongue weight. Some people will also use 12-15% of the trailers GVWR for their calculations. That way if you're ok at max, you'll be ok at any trailer weight under that.

It also includes 150 lbs for driver

Also:

The lipstick need only be counted if you're not wearing it. :B

No it doesn't. The tow rating includes 150lbs for the driver, payload does not account anything for the driver.

Oh my Gawd! My dry weight on my trailer is 5,628 and I called StarCraft and they told me the hitch weight was 718. Are you saying that if I add 1,000 pounds inside the trailer that some of that 1,000 (12-15% of it) must also go on as hitch weight? Because if that is what you are saying then I would have to subtract 130 pounds more from the payload? Lets see...1580 (claimed payload) -150 (me)-120 (dogs)-130-718 (tongue weight). That leaves 462 and I don't even know what the receiver and ball weigh or what else I might put in the truck. I am kind of light on travel but still.

Gal;

Your thinking is absolutely correct. There are a few assumptions in there, but the fact is, you are probably going to be over the payload capacity of that Tundra. Most would say that a few pounds over is not a big deal, me included. However, I don't like being ten or twenty percent over what Toyota specifies. More truck or less trailer would be my advice. The biggest assumption is that hitch weight of only 718 pounds. Your trailer could weigh over 7,000 pounds when loaded with a tongue weight close to 1,000 pounds. Need to verify all weights involved, except the lipstick.

You got the right idea. However, be aware that the posted payload rating for your truck (1580 lbs) may not be all that accurate as the dealer may have installed some options or maybe even you have.

Your best bet is go down to your local scale and weigh your truck with a full tank of gas and without you in it. Then subtract that amount from your truck's GVWR and that's what you will have for an "actual" payload figure.

Then EVERYTHING you put in or on it...will reduce that figure by that amount. When we had our Tundra and a 26' TT, we weighed everything on a bath room scale...even the tongue weight....to make sure we were within limits. I gotta admit, there were times when we were several hundred pounds over the payload, but the truck handle it pretty good. We did, however, eventually installed a supercharger on the engine for another 100 hp or so. Made a big difference on the hills/mountains.

Boy-oh-boy. That payload is some important stuff, isn't it? I wonder if the Nissan Titan has a higher payload.

Well. A half-ton just isn't going to work out. All I can afford is a used truck and I just don't know if I can bring myself to buy a 3/4 ton used American made truck. Please don't jump on me. I've read the Consumer Reports and they just don't seem to have the reliability that Toyotas and Nissans do. At $16to $20K all I can get is probably someone's truck with 100,000+ miles on it. I'm uneasy with that.

Are you giving up on the Tundra?

I for one think it may well tow your trailer, depending on its real weights. Tongue weight needn't be as high as 15%- ten percent of trailer total is probably more typical.
