Does the cargo capacity weight on the driver side door jam already take into account the weight of a full tank of gas and driver? For example, I have a 36 gallon tank. Do I deduct the weight of the gas (6.3 x 36 = 226.8 gal.) from the 1,379 lbs shown on my sticker? That gives me only 1,152 lbs for cargo, tongue weight, etc.

 

It includes full tank of fuel only.....not the driver, the add on tonneau cover, the new Weathertech floor mats you bought or anything else put in/on the vehicle after it left the factory.

 

Having 'been there, AND doing that'.....I have come to realize that when you start looking up how much a gallon of this or that weighs because you feel it necessary to work it into your trailer weight calculation, it's time to go with a Super Duty!

 

No.


If your "Tire and Loading Information" label affixed to the driver door jamb states "The combined weight of occupants and cargo should never exceed: ...1379 LBS" then that means beginning with no occupants but a full tank of fuel you can add up to 1,379 lbs.

Here's what you do: Throw everything into the truck that you'd carry along with the trailer, then, without the trailer, head over to the nearest truck stop and weigh your truck. Take the GVWR of your truck, then subtract what your truck weighs with everybody and everything in it... from your GVWR. You'll need to leave some on the table; a lot, actually, for trailer tongue weight.

 

Yep, 1379lbs is NOT a good payload capacity for towing a RV.
yes, fuel only is included in payload capacity number, any occupant(including driver), truck cargo, non-factory equipment added and WDH weight reduces that 1379 number by its weight. then you have to calculate loaded tongue weight(NOT dry tongue weight) and subtract that also.

 

I weighed my truck with a full tank and me in it, came in at 5,480. That leaves me with 1,020 lbs. to play with. If the GVRW of the TT is 6995 (that's loaded, correct?) x .13 gives me an additional 111 lbs in my truck. This assumes I load the trailer to it's max capacity. Correct?

 

That is correct but understand that is only an approximation.

I recently was looking at what I thought was my next trailer. 6995/7495 (Depending on build date) GVWR and a listed Dry Tongue of 515 lb. After talking to a couple of owners it was not unusual for it to go 7000 lb with just fresh water and a weekend load. But the deal breaker was a tongue weight exceeding 1200 lb (17%) was not unusual.

 

If you've got 1020 lbs usable payload a 4000 lb trailer is about all you really want. That's 520 lbs on the tongue and 500 left over for you, passengers, and cargo. And 500 lbs doesn't go far. My wife and I combined are 360 lbs.

 

I don't think I can find a decent trailer in the 4,000 lb range. I am getting the feeling I have a truck that won't pull anything but a small boat or utility trailer!! Sheesh....

 

No, Payload Capacity ONLY included full fuel tank, NOT the driver. so you have to subtract your weight from the 1020 number.
Towing Capacity includes a 150lb driver and full tank.
