There is a
Cat Scale within 12 miles of Fairborn. A Cat Scale are usually at a truck stop. Go in first and ask how to weight and that you want two weighings. Take a broom with you :). You will see when you get there.
A Cat Scale has three different platforms to give you the weight of the front axle, rear axle, and the weight of the trailer axles.
First you weigh only the truck with a typical load in the back and passengers. You will get a slip with the weight of front and rear axles.
Then hook up the trailer with the WD bars and return to the scale and you get all of the above weights. The weighing will cost less than $15 for both weighings
The idea of the WD is return the front axle to its unhooked weight.
One of our RV Net experts explain how to set up a WD. You can read it here
WD Setup. You can also PM the poster and he will help.
What weight are the bars specification
Looking at your picture, it appears that the front of the truck is high, indicating that your WD hitch is not transfering enough weight to the front axle. Not that your truck needs to be level. A trip to the Cat scale will tell you what you need to do.
What most of us do, is to raise the tongue attached to the truck to make it easier to hook up the spring bars. An electric jack makes it much easier to do this.
Good Luck and post back what info you get.
