I have been doing Travel trailer/tow vehicle calculations and have become familiar with this. It is VERY confusing(for me at least) unless you have a ton of experience with it.
Your truck can hadle max load of 5400 including any tongue weight from a trailer. The max frt and rear weight are not to be combined for total capacity. They are there for reference to tongue weight and weight distribution calculations. For example your truck weight 4000 lbs(??) you could put a total of 1400 of load(including gas and people) on the truck(distributed-not all in bed).
If you were towing a trailer(with truck empty) you have to know the tongue weight(usually 500 or less) of the trailer and the current rear axle load. Lets say it's 1800lbs for example. Add your 500 trailer tongue weight to 1800=2300lbs rear axle weight and total vehicle weight of 4500 lbs. Well under your max rear axle and vehicle GVW, so you could also haul another 600lbs+ of cargo and people in truck in theory.
I found this explanation of terms on google.
Weight Definitions
Actual Weights
There are several different types of weights. First, there are actual weights. These include:
Curb Weight: The weight of the vehicle including standard equipment, oil, lubricants and a full tank of fuel. Does not include optional contents or other optional equipment, the weight of driver, passengers or cargo
Option Weight: The weight of any added equipment that is not included in the base curb weight
Passenger Weight: Defined as 150 lbs. multiplied by the number of seating positions, including the driver, that the vehicle can carry
Payload:
Gross payload is defined as the weight of all passengers, options and cargo
Net payload is defined as the weight that can be placed in the truck after subtracting for passengers, optional equipment and cargo.
Gross Vehicle Weight (GVW): The weight of the vehicle including passengers, options and all cargo
Trailer Weight: The weight of a trailer including all attachments, lights, etc.
Gross Combination Weight (GCW): Gross Vehicle Weight plus the trailer weight
Gross Axle Weight: The weight loaded on the front or rear axle
Tongue Weight: The amount of the trailer’s weight that presses down on the trailer hitch (usually 10-15 percent of the trailer’s weight, approximately 25 percent for fifth-wheel applications). Second, there are weight ratings. These are not actual weights; they are ratings that must be adhered to:
Payload Rating: This is the advertised payload rating. It is the maximum allowable payload for the truck
Allowable Weight: The maximum amount of weight that can be placed in the vehicle after subtracting allowances for passengers and options
Gross Vehicle Weight Rating (GVWR): The maximum allowable weight of the loaded vehicle with payload
Gross Axle Weight Rating (GAWR): The maximum allowable weight to be placed on an individual axle. Gross Axle Weight Ratings are provided for both front and rear axles
Gross Combination Weight Rating (GCWR): The maximum allowable weight of the vehicle, its trailer and all associated passengers, cargo and equipment
The point to remember is that the actual weights should never exceed the listed weight ratings.
