Weighed my Wildwood & Tow vehicle and am confused...

Took my 2011 26tbss and 2005 F 150 XLT to the scales yesterday and the weights are confusing....

Weighed front axle = 3,200 lbs (GAWR 3,750 lbs)
Weighed Rear axle with trialer hitched = 3,400 lbs (GAWR 3,830 lbs)
The operator said my tow vehicle weighed 6,880 lbs.
Trailer weighed = 5,420.

Total came to 12,300 well under the 15,000 GCWR of my tow vehicle.

Tounge weight is listed at 600 lbs.
I was alone, I weigh 230 pounds and half tank of gas (90 lbs).

My GVWR = 7200 lbs, I subtracted the weight of 6,880 and I came up with 320 lbs for gear and family? is my math correct?

According to ford, the base curb weight of my 2005 Ford 150 XLT is 5,471 lbs.

If I subtract the weight 5471 from the weight of 6,880 = 1409.

Now from that 1409 lbs I took my weight of 230 lbs and 90 lbs gas that comes to 1,089 lbs. Does this mean the tounge weght is 1,089 lbs???
I am using a WDH.

Any help would be appreciated!
Bill

hmm never weighed up a truck/trailer before with a WDH on it.. only way to know exactly what your tongue weight would be is to weigh the truck separate and then weigh your trailer separate then get those #'s then hook it up again and weigh it and see what the difference is.

a wdh is a little tricky in the fact it will transfer some weight to your steering wheels in the process of trying to keep the truck/trailer rigid and a little more on your trailer wheels to accordingly.

You need to go back across the scales without the trailer hooked up, and as close to possible as with the load as when you weighed in with the trailer. The difference will give you the (adjusted) tongue weight. To get a true weight, you would have had to unhook the spring bars during the initial weigh-in.

My Certificate of Origin lists my truck as weighing somewhere in the 5300 lb. range, but with me sitting in the drivers seat (190 lbs), a few items in the bed, and my some personal belongings in the cab, I come across the scales in the 5900 lb range. You may be able to put a little more weight on the front TV axle and trailer axle, giving you a little more cargo carrying capacity with the truck.

Overall, your figures look pretty good.

Also, the listed tongue weight of 600 lbs. has probably grown some.

When you go back across the scales, again get the front and rear axle weights. That way you can see if your WDH is setup properly.

I have gone across the scales with no spring bars attached, with spring bars attached, and with just the truck solo to come up with my weights.

You don't really need to weigh the trailer on its own. With the WDH unhooked, go across the scales, weighing the TV front axle, rear axle, and trailer axles. Go back across with just the TV, again weighing each axle. The overall difference is the total trailer weight. Weighing the truck alone, the difference between that and the previous weight of the TV with the trailer would be the hitch weight. You could also calculate the hitch weight my taking the total of the combo, minus just the TV, and again minus the trailer axle weight. What is left is the tongue weight.

With 3 trips across the scales (combo with no spring bars, combo with spring bars attached, truck alone) and weighing each axle, you can get all sorts of information.

For example, here are the stats I got for my rig: Weight Stats

To take some weight off of the hitch, could I fill my gray and black tanks (each 35 gal), which are located behind the second axle on the trailer (trailer has 2 axles). the water would weigh 560 lbs, since this would be lifting the front of the trailer would this take 560 pounds off of the TV, or would the WDH prevent this from happening?

BTW thank you for your suggestions, I am off tot he scales now to weigh my TV.

In reality if your tanks are behind the axles, that would take weight off of the tongue, but I can't imagine traveling with those tanks full....that is a lot of weight to pull. I also did tongue weigh-ins (with tongue scale) with different fluid levels, and will see if I can find those.

It will be interesting to see what your next weights are.

Here is how the tongue weight reacts to fluid levels on my trailer:


Water added to fresh water tank (30 gals.): -20 lbs.
Water added to water heater (6 gals): -20 lbs.
Fill gray tank (30 gals.): +40 lbs.
Fill black tank (30 gals) : +80 lbs.

My fresh water tank sits over and behind my rear axle, the gray water tank sits directly in front of my front axle, and the black water sits directly in front of that. My water heater sits in the extreme back corner of the camper.

Hey, Thanks for all the replies! Well, went back to the same scales to wejgh my TV, I told the employee I wanted the weigh tof the front and rear axle. He says ok, it will be one weight, the total of your TV. I said, no, I want a sepperate weight for the front, and a second weight for the rear. he says, uh, I don't think we do that. I said I was here yesterday and your fellow employee weighed my truck and trailer. He said, you can try weighing it the way you want. So I tried, front axle on one scale and the rear axle on the other scale......He tells me there is no reading, so my truck must not weigh enough, you know we are used to weighing large rigs, your truck must not weigh enough, come back in the morning with your trailer and we might be able to weigh it. So, I will call the scales in the morning and ask them whet their minimum weight is and go from there.

Bill
