Wdh question

I was wondering if anyone has measured the actual weight re-distribution when a WDH is properly set up.

Tow Vehicle's Front and Rear axle weights with trailer hooked up, no bars tensioned.

Tow vehicle's Front and Rear axle weights with trailer hooked up and bars set up ready to tow.

Just curious on how much actual weight was taken off the rear axle of the vehicle and how much was added to the front axle.

I understand weight will be moved to the trailer also but I'm only looking at the tow vehicle. Weights would have to taken at a truck scale for accurate effects.

Thanks Wireman

It's been done many times with a CAT scale.

Do a search for CAT scale

Yes, I have, just like many here and over on RV.net.

BUT, the question it seems you are asking has huge variables. It will vary based on loaded tw, model of tv, the tv manufactures suggested wdh set up (25%,50%, or 100% restored lost weight), and how each tt is loaded.

I don't have the figures handy, but search my posts for another member asking about a 32 BHDS, believe I posted the weights there.

You are 110% about a visit to the scale. I was surprised by my first results. I was about 50% of the Max trailer weight, so I was welllllll within my weight limits, right? The surprise was I was about 200# below the Rear GAWR with just the Bride, wiener dog and myself. Add another couple and their gear and we were over. Not an extreme over weight condition but definitely over.
It would be convenient if dealers had scales. It could be a help to new shoppers and during the PDI. Oh yeah, and frogs need wings too.
Anyway, the CAT Scale is your friend.

FWIW, Wireman, I'm taking my 23RLSW out for the first time in just a couple of weeks, and part of my plan for that trip is a CAT scale visit on the way. We're lucky to have one within a couple of miles from my home.

Good luck!

weight distribution hitch is for safety, more control of vehcile my tt is 4700lbs. Nissan has a sagging problem on rear suspension no idea why coil spring is soft for 5000lbs towing capacity so with WDH helps, although went to scale surprised 460lbs on hitch and trailer loaded was abou 4400.. didn't have much stuff really.

You will achieve the same results by just measuring the front fender well. All vehicle MFGs state how to setup your tow vehicle in the owners manual.
They will tell you what % you need to return the front to.
It will be either 100% return or 50-100% return.
If you know the trailers TW and buy the appropriate WD spring bars you should be able to setup the tow vehicle by measuring.
