You have to drive off the scale, go to somewhere on the lot and unhook. Then go back across the scale and ask for a re-weigh, doesn't cost anything on a CAT scale. Then compare the numbers on the truck axles. The differences are the pin weight. If the front axle drops 500 lbs and the rear 2000 then the pin weight is 2500. The trailer weight won't change if it's level on the truck. It don't know if the pin box is on the truck or it's on the front legs.

Why are there so few posts with the real tire by tire loading? I know it takes a bit more effort but how do you know your fully loaded axle split is 50/50 not 45/55?
Also how do you know your side to side split on each axle is 50/50 and not 35/65 as I have seen in some extreem cases?

Just wondering..

Probably because CAT scales are everywhere but scales to weigh each tire are rare. Besides if the trailer is standing up straight it has to be fairly even if the springs are identical, especially with the 13' tall 5vers.

Usually, there is a $1.00 reweigh fee at CAT Scale at the same location of the original weigh. For the best "how to weigh" information, consider visiting Fifth Wheel St..

Just found out mine, trying to find where the weight is.....

TV 2007 Chevy CC D/A 4wd Dually with hitch, full of fuel, toolbox, 2 adults, 2 children, and dog. 8240lbs

5th Wheel -2007 KZ Sportsmen Sportster 37KGX3 - sticker weight dry 11,556. Sticker GVWR is 16,940. Actual scaled weight with all our clothes, food, etc and a golf cart, DRY!, 19,120. Sticker hitch weight 2940, actual 3520. I don't see a problem here. Looks normal. However the total weight on the axles is 15,600... that's 1,600 over the axle rating and 600 over the tire rating. I am at a loss. I hope it is scale error. I will be reweighing this weekend.

Total GCWR 27,220!!! Truck rated at 23,500. I have no idea where the weight is. I can only hope that the scale was wrong. We did not load 7500 lbs of gear in here. Not to mention the fact that all tanks were empty and I have a 110 gallon fresh tank.....

Some things I consider when sizing:
1.sticker dry weight on 5th wheel does not usually include options - it varies with manufacturer, and the year the trailer was manufactured whether they included options or not in the weight. Cannot be trusted when one is cutting it close. Weighing is the only way to go.
2.One should not exceed the TV payload weight, no matter what the sales people say. So by the time you add the hitch weight of the 5W, the bed liner, the 5W hitch, cargo, wifey and kids, dogies (i have 2) and stuff, you may have actually exceeded that as well.
3. One should also not exceed the tire rating either.

I check the following before I am satisfied
1. Tire limit
2. Axle limit
3. Payload Limit
4. GCVR limit

Looking at the pure numbers, I would reconsider the configuration.

Not sure who Phalynx is but hoping the scales are wrong is not a good position to be in. There should be some state or county certification sticker / certificate available as truckers can be fined if they are found overweight so they have to have reliable scales.
Unless he weighed the trailer when new and empty there is no way to be certain of it's empty weight.
This is not a good situation.

I had a 1997 & 2002 Dodge CTD with the 3.55 gearing. I found it to be "too tall" for towing but downshifting lessened the pain when I hit the hills. Good luck. That looks like a good combo.
