If you are doing a bumper pull with a WDH, it's a good idea to do a 3rd weigh (again $2.50) with the tension released from the bars.

I have seen this advice many times but have never understood what useful info is gained

1st pass WDH spring bars attached shows you how the weight is distributed between the trailer and the trucks 2 axles.

2nd pass no spring bars shows how the trailer loads the rear axle of the truck and lightens the front because of the tongue weight which you can find from the 3rd pass.

3rd pass truck only.

To find tongue weight subtract the 3rd pass from the trucks weight you found with the second pass. That difference is the tongue weight.
You can determine how much weight the WDH is distributing by looking at your front axle weight of just the truck alone and when you have the spring bars connected. I like no more than a 100lb difference between truck alone and truck with WDH spring bars connected for the front axle.

hope this helps
