TRD Pro - payload capacity?

[LostInAZ]

Your wife is gonna get the 4Runner in the divorce settlement. The tipping point for the judge will be when she shows the judge that you were posting her weight in the 4Runners forum.

Nah, she's proud of that weight after 25-years of marriage. Now, I have to get my fat ass back to my honeymoon weight.

Different vehicle, same concept. I loaded my Ram 2500 with the items I normally carry every day (spare fluids, ice scraper, basic tools, etc.), added myself and a full tank of diesel, then weighed it. I subtracted that weight from the GVWR, and the result is my available payload. That remaining payload has to account for everything else I add, including passengers, luggage, trailer tongue weight, cargo, and so on.

I'll do the same thing with the 4Runner. That eliminates any concern about what Toyota did or didn't include in the published payload calculation.

Technically, GVWR is the absolute limit. Your actual available payload depends entirely on how you've equipped and loaded the vehicle. If your daily load includes skid plates, a full fuel tank, yourself, your partner, your dog, a refrigerator, or anything else, all of that consumes part of your payload, regardless of an ominous and vsgue curb weight. You determine your curb weight. If you were to leave those items at home, then your available payload increases accordingly, but the vehicle's GVWR does not change.

In theory, you could remove the rear seats, spare tire, carpeting, install a lightweight battery, or even replace the windows with cardboard and increase your available payload. The vehicle would weigh less, so you'd have more capacity before reaching the GVWR.
The GVWR is generally not an indication that the vehicle will immediately become unsafe if it exceeds that number. Rather, it is the maximum weight at which the vehicle has been certified and tested to meet applicable safety and regulatory standards. There is undoubtedly some engineering margin built into that number, but there is no practical way for the owner to know how much.

It's also true that regulatory requirements, including EPA emissions classifications, can influence the chosen GVWR. Manufacturers sometimes have incentives to certify vehicles within particular weight classes, but regardless of how the rating was determined, the published GVWR remains the limit owners should use when loading the vehicle.

Or don't and you can be a test driver.
