1st time using Cat Scales, need help analyzing results

I took the time to get my rigged weighed today before we head to Yellowstone this week and could use a little help figuring out my tongue weight. The weighing process went pretty easy except for the 1st pass through, they took my weight before I could get back into the truck, so all weights I post are WITHOUT me in the drivers seat (210 lbs)

Here is what my truck is rated for

GAWR FRT 5200lbs
GAWR REAR 6010lbs
GVWR 9000lbs
GCWR 20000lbs

1st weigh truck and trailer with WD (without driver)
STEER AXLE 4500lbs
DRIVE AXLE 4720lbs
TRAILER 8200lbs
GCVW 17420lbs

2nd weigh truck and trailer without WD or driver
STEER AXLE 3820lbs
DRIVE AXLE 5740lbs
TRAILER 7860lbs
GCVW 17420lbs

3rd weigh truck only without driver
STEER AXLE 4460lbs
DRIVE AXLE 3680lbs

1st thing I saw was the truck is 220lbs plus my 210lbs overweight. The truck is fully loaded for the trip with a full tank of fuel. There's maybe a 100lbs I could shed in the bed but not 430lbs. The camper is fully loaded except maybe 100lbs of food/clothes

Now tongue weight, is that 1st weigh steer+drive weights minus #3 steer+drive = 1080lbs? or am I doing that wrong?

Does anyone see any other potential risks or things to be concerned with? Btw, it was about a 45min drive on the highway to the scales, and I don't think its ever pulled better. Thanks for the help

  • A couple thing I left out, GVWR for the camper is 11000lbs, I have Timbrens on the truck, not that they help vehicle GVWR apparently, and the truck and camper both have E-rated tires (3165lbs each on the truck). I weighed everything I removed from the bed just now, and moved that into the camper (124lbs). What I don't understand is, why isn't vehicle GVWR the sum of adding the 2 axle ratings?
  • Gravyd, those with more time on their hands than I, will analyze your numbers . However, what I find interesting is that you are over on the one number that I find most important, GVWR. I am not being critical but it does go to show us that even a 2500 is not unlimited when it comes to towing travel trailers. Thanks for posting the information and have a great trip to Yellowstone. Just don't haul any five hundred pound bears home, as you are already over on your payload.
  • All the talk about weights and me having some problems towing the first trip I got a WD hitch and took it to the scales empty today. I think I am a notch high on the hitch and have dropped it to the bottom.
    Here are my numbers:
    Salem T25 toy hauler behind a full size Ram 2500 Quad cab 6.5 bed.

    Trailer ratings
    GVWR 10588
    GAWR (each axle) 5080

    Truck rating
    Total GVWR 8800
    Rear GVWR 6000

    Truck weights-empty (measured)
    front 3600
    rear 3100
    total 6500

    Truck and trailer (trailer dry measured).
    truck front-loaded 3200
    back truck loaded 4550
    RV Duals 6100

    truck with trailer weights 7750
    truck without trailer weights 6500
    tongue weight 1250

    What I noticed was that my steering axle actually got lighter (so not enough tension on the WD correct?)
    If I have a 1000 lb receiver I am also overloaded with a dry trailer correct?
    Will one more chain link correct this?
    Still does not pull worth a crap.
    Sorry for Hi-jacking this thread but seems like fits right in or feel free to move it.
  • It is the weights without the WDH

    9560-8140=1420 tongue weight.
    Trailer weighs 9280
    Tongue weight percentage is 15.3%

    Imho, if you feel comfortable with your setup, keep it as is.
  • YES you are over trucks GVWR BUT
    you are under FAWR, under RAWR, under GCWR

    Other than checking rear tire ratings IMHO you are good to go

    Yes..tongue weight is difference between truck/trailer weights minus trucks weights.
