Hello all. First time weighing our rig after almost a year full time

2022 Ford F-350 Crew Cab 8' bed Dully Diesel 2x4 XLT
2022 Durango Gold 391RKF 42.5 foot 5th Wheel

Full tank of fuel (48 gallons). NO fresh water, grey tanks empty, black tank had maybe 15 gallons. Fully loaded like we normally do.

Truck had my wife and I, plus 3 dogs in crates in back seat. Portable Generator, and portable waste tank with 3 dog X-pens in bed. 2 bikes and an aluminum ladder on back of trailer.

CAT Scale numbers. Truck and Trailer
Steer Axle: 4,800
Drive Axle: 7,260
Trailer Axles: 13,400

Total GVW: 25,460
------------------------------------------------

CAT Scale numbers: Truck ONLY

Steer Axle: 4,760 (diff of 40 lbs)
Drive Axle: 3,960 (diff of 3,300 lbs)

Gross: 8,720

If I did this correctly, this is my trailer gross and pin weight. Pin takes some of the weight off the trailer axles.

GROSS: 25,460 - 8,720 = 16,740 for trailer gross weight

Gross of Trailer 16,740
Trailer Axles only - 13,400
------------
Pin weight = 3,340


Truck specs as taken off door sticker:
GARW Front : 5,300
GAWR Rear : 9,900

GVWR: 14,000

KZ Spec Tag

STOCK Trailer Gross Weight Rating: 16,000
STOCK Cargo Max: 2,850
STOCK Dry Hitch Weight: 2,570

Of course, KZ doesn't weigh each unit getting ready for shipment nor does the dealer after adding his or customers options.
I have no idea what the stock axles weigh nor do I know what the new axles weigh, same for the king pin.

I have the Flex Air pin box with a rating of 16,000 lbs
5th wheel Reese Hitch with a rating of 25,000 lbs


---------------------------------------------

We have a "Flex-Air" pin box
MORryde 7,000 lb independent suspension with disk brakes. These axles are heavier than the standard


Are we good, or bad?

Looks like the trailer is 740lb overweight.

Doesn't mean an instant failure but don't be shocked if it does.

I've been told that part of a 5th wheel's weight sits on the Truck. Reason to subtract part of the trailers axle weight numbers. So, if my numbers are now correct, 16,740 minus axle weight of 13,400 is what's sitting on the truck, which is 3340. If I could get away with it, I'd drop the trailer on the scales by it self but you can't do that at a CAT scale

Well your math is correct and based on specs you are 740# over the trailers GVWR. Likely pretty hard to lighten the trailer 740#, listed cargo capacity of 2,850# and 740# over gross total 3,590# of stuff. Putting it another way you are about 21% over your cargo capacity.
