OK, here are the results. They would not let me weigh my trailer by itself. They told me I could not uncouple it on the scale so I only got the truck and trailer hooked up and the truck by itself with no occupants, a full tank and my wd hitch attached.

Loaded
A1 - 3340
B1 - 3240
C1 - 5180

Unloaded
A2 - 3340
B2 - 2860

According to that, my tongue weight is only 380 which blew me away because I have a tongue weight scale and it weighs 572. I still didn't believe it was right so I double checked the 572 with the old bathroom scale trick and it was spot on. It looks like my WD hitch is transferring about 35-40% back to the trailer. I was figuring my payload with a tongue weight of almost 600. I was pleasantly surprised to realize a had a couple hundred pounds of margin in there.

There is something strange here. You front axel weight the same with or without the trailer and WD hitch engaged? Or am I missing something? Also, your unloaded rear axel is heavy, do you have a 157WB?

Oh, even if it not very important, your tongue weight is 380 and not 360 ;-)

Yeah, I expected the front to be heavier while loaded. When I hook up w/o the bars my back drops 1.75 in and the front lifts up .5. With the bars the back drops .75 and the front drops .125. Maybe it really is staying close to the same.

As far as the back axle, I had 2 car seats and 2 full size strollers in the back along with my bed rug and a G2 cover. The tank was also full so maybe that had something to do with it? What should it be? The truck is a 145 Platinum SCREW EB

That is surprising but I don't know much about those fancy WDH hitches. If your tongue weight is almost 600lbs, I was expecting at least 150lbs to be transfered to the front...

I'm not saying it is not correct, I was not expecting it to be that high. But if you look at it, it makes sense since a with a 145WB Screw, the cab is very close to the rear axel. My empty SCab is a good 400lbs lighter on the rear axel.

Cheers

My unloaded rear is 2660, so his 2860 doesn’t seem that far off with the bed rug and cover and such.

If the front hardly moves, it makes sense that the unloaded and loaded weights are the same.

Bummer they wouldn’t let you weigh the trailer by itself.

However, you found out what was important – how much weight you’re carrying on your axles.

On a side note, after my trip this weekend, I’m pleased to say that I *finally* got my WD setup dialed in. Front end stays the same height and the trailer is level. I should hit the scale again and see what my numbers are.

Plus, I forgot to mention that I left my WD hitch and bars in my receiver when I weighed the truck empty so that is another 100#

I think this is the first discussion I see with people stating real actual numbers...

Both of those numbers are pretty surprising. What are you guys driving (Scab, Screw, 5.5' box, 6.5' box, 4x4, 4x2?). In Ontario our trucks get registered at a standard 3,000kg (6,600lbs) minimum unless you ask to up your RGW (Registered Gross Weight; total weight your truck and any trailer/load/cargo transmit to the road; think cab card allowables for big rig drivers). I'm surprised how little room we have for cargo before we exceed our RGW. Might have to bump mine up a little, haha.

I'm driving a plain Scab 2012 FX4 and according to my registrations my official weight is 2457kg. Of course this is empty and it seems pretty accurate.

No way an empty F150 weight 3,000kg... Don't know where this come from.

Cheers

Empty weight (typically) comes from the manufacturer and is only the weight of the cab and chassis (no box), no fuel, no passengers or cargo. In Quebec, you guys pay for your val tag based on how many axles the vehicle has but in Ontario, our "RGW" is what we are allowed to transmit to the roadway. It looks like these trucks weigh somewhere around 2500-2900 kg which leaves you only 100-500 kg to put in the truck before you're over your registered gross weight. $$Fine$$ time if you get popped.
