Proper way to weigh rig? Scale update.

Since the OP started a new thread on this topic I am going to close this one. You can see his new thread here.

If the "revised" values are:

_______________Front____Rear
Truck only_______3620____2820
Combo wo/WD___3500____4240
Combo w/WD____3400____4120

it's impossible for the front axle load to decrease by 120# while the rear increases by 1420#.
And it's impossible, when WD is applied, for the front axle to decrease by another 100# while the rear axle decreases by 120#.

I recommend a complete re-weigh (all three sets with no changes in loading of TV or TT) if the OP really wants to know how much load is being transferred.

FYI - When you opt to "re-weigh" the same day on CAT certified scales, the fee is only $2 per re-weigh. Please be aware so toy don't over pay!

Close. I really need to get off these day/night rotations. I forgot to include my truck re-weigh in my 9:20 am post from today.

Truck alone today.

Front Axle: 3620#

Rear Axle: 2820#

Total:6440

"Guessing" that your unladen front axle weight is around 3,500 pounds, you are well within what Chevrolet currently requires for Front Axle Load Restoration on a 2500 HD. Some will say that "more is better", of course.

Yes I will need to go back. In my fear of the lightning, hail and 50 mph wind I completely forgot to move the truck off the scale when I weighed unhitched. Also after I weighed just the truck this morning the assistant manager (Kwik Trip) recognised me from the previous day. During our conversation about the tornado that passed thru shortly after I left, he pointed out that the attendant the day before probably had measuremanents with me standing at the front of the truck instead of in it. So this could throw some of the numbers off.

Here are numbers from when I weighed it when I first picked it up 18 20 months ago. I have added one more washer since then.

TT and truck with WD on:

Steer Axle: 3300

Drive Axle: 3920

Trailer Axle: 7120

Gross: 14340


TT and Truck with NO WD:

Steer Axle: 2940

Drive Axle: 4420

Trailer Axle: 6980

Gross Weight: 14340

Long story short, forget all the assumptions and go back to the scales when it is not storming. The three weighings required have been posted often.

The numbers as posted, don't make sense.
However, it looks as though the trailer was on the scales during the "Un-hitched from truck" weighing. If so, the tongue weight probably was included in the "un-hitched" rear axle load.

If we assume the tongue weight was 1000#, having the TT attached with no WD should have removed about 400# from the front axle and added about 1400# to the rear axle.

If we assume the "un-hitched" rear axle load really was 3980-1000 = 2980#, that would give a more realistic load.
And, if we add the OP's 280# to the 3520# front axle value, the resulting 3800# would make more sense for the "un-hitched" front axle.

The decrease in rear axle load from 4240# to 4120# is consistent with a TT axle load increase from 7360# to 7400#.
However, the front axle load should have increassed by about 80#, but the data show a decrease of 100#.

I think it's safe to say the tongue weight is around 1000#, but if you really want to know, you need to do the weighings again.
Next time, you should not have the TT on the scales when you do the "un-hitched" weighing.
Also, try to ensure that all people and cargo remain in the same locations for all weighings.

I am curious, I see where you edited your post. What did you change? I still see a nearly 300 pound change in the Total weight.

He didn't change anything except put spaces between the sentences to make it easier to read. The wording and numbers are exactly the same except he added the stuff at the end about clothing and food.
