If set up properly the rear shouldn't be lower than the front, if it is, you have too much weight back there. Correctly setup, front wheel fender height should be at or near the empty height, and the rear should be less than 2" lower than when empty. After setting up several trucks with WDH, the all came out pretty much like this.

The only one I have had problems with, even when setup exactly this way is my current 2016, BUT I have a feeling it has something to do with the steering on the truck, and nothing to do with the trailer or hitch since I can replicate the handling with weight in the bed and no trailer.

I think his point was that if you hook up the trailer and WDH, then inflate the air bags and raise the rear of the truck, it unloads the WDH bars and reduces the effect. Instead of relying on the WDH to transfer the weight you are relying on the bags to support the tongue load.

Pretty sure the bold part goes against the setup recommendations of both Ford (hook up with no bars then return 1/4 of the way to unloaded height) and hitch manufacturers (hook up with no bars then return 1/2 way to unloaded height). My 2011 manual said to return 1/2 way. Not sure why Ford changed it but they did.

Set up my 2011 that way and it was stable. Set up my 2015 the same way and it was stable as well.

I will say the hitch makes a world of difference. If the hitch he has is a round bar (with 'L' shaped bars) and chains, it has no sway control and probably is not that great a hitch. I had one of those at first with my 2011 but swapped to a Husky Centerline TS before a 1400 mile trip and the new hitch was so much better. When I got my new truck it took only a small adjustment to set up properly and the 2015 was stable as well.

My advice would be to invest in a better hitch (Centerline TS, Equalizer 4 point) with built in sway control and get it set up properly first.

The end goal is to return the weight to the front axle. So if your empty front axle weight is 3240, you want to return it back as close as you can to 3240, and to do that, you need to return the front fender to it's original height. The numbers I have on my truck show that going only halfway back to normal, I move half the weight back. When I do that, it doesn't handle as well, but if I return it to it's original height it handles properly(Based on my 2014).

The best explanations of the difference between lift and weight distribution I've seen to date:

Wait, you are just towing a pop up and need LT tires, a WDH and Roadactive? BTW, this thread last had a reply 5 years before yours. You may want to start your own thread with a specific question regarding towing your camper.

No, I want to upgrade to a 30’ trailer, 6500lbs dry, 696lbs tongue. I want to make sure it is as stable as I can reasonably make it.

oops i have no idea why I replied here clicked a link to reply to my original post. Ahh it’s the format of you keep scrolling on your own post it brings up other related and I missed it. I will remove my other reply and put it where it belongs. Sorry.
