Russ661 Judging by the photo, your truck and trailer are both nose high. You need to drop the ball height to get the trailer nose down then adjust the WDH chains to get the truck level. Be aware that as you put tension on the spring bars to level the truck the nose of the trailer will move up so my advice would be to start with a ball height that puts the trailer just a bit low, about an inch, and go from there. Remember too that the trailer tongue weight will make the rear of the truck sag a bit so figure that in when setting up your initial ball height. On most WDH the tension bars should be very close to parallel with the trailer tongue rails when you are finished. Hope this helps, good luck.

Grit dog It's not the tires. Wish you lived closer, I'd take all your cast off "bad" tires!
Concentrate on the trailer/truck setup.
And as usual with most new deep lug tires, don't judge the tire's performance for the first 1-2,000 miles until they get the wiggles out of them!

SAP2018 This is how my trailer sits with the air bags at 20psi and 9 free links on the blue ox WDH

A WDH is a better solution but sometimes it's not enough. Sometimes they need a little help.

A WDH also puts weight back on the trailer axles. Airbags can't do that very well. They do it a little bit by lifting the tongue but that's not the whole solution.

The OP needs to change the pitch of the truck, IMHO. One way or the other.
I'd be curious to see those test results. For some reason I just can't picture large amounts of weight shifting as a result of changing the angle by a few degrees. Not even if raising the rear by a foot, as I suggested above in an exaggerated example.

Also, I don't understand why a properly sized and adjusted WDH would need any help. The WDH should lift the rear without needing any assistance from air springs.

And, I don't understand how lifting the tongue a little bit (with air springs) puts any noticeable extra weight on the trailer axles. Unless that weight shift is as large as you claim, and/or there's a cluster of large A/C units on the roof of the trailer, right over the axles.
Then it's also a matter of if the trailer has torsion axles or not, and if so, how level it is in the first place.

That's a job for a weight distributing hitch.

Yes.

Airbags don't hurt but a WDH is more gooder for a pull behind.

If his end is tilted up 90 degrees, ALL of the weight shifts to your end.

Same principle holds true with cars/trucks.

By taking too much weight off the front end, the steering becomes 'light' and has less control over the vehicle.

He needs to get that front end down, IMHO. Airbags or no.



The physics in relation to carrying a couch upstairs is true. However, relating it to this situation is not because the fulcrum point is between 2 forces which is why his front end lifts with or without bags. A properly set up weight distributing hitch will with anti sway cams like already suggested will solve the issue. They are so effective that overkill bars can be tightened up to the point the rear of the truck will lift above ride height and the front will squat.

Yes. I have the factory air bags and they don’t transfer any significant weight back to the front axle according to the scale.

Danderson The proper wheel width helps heaps.
I'm going from 8" stockers to 9" wide as recommended for a 35" Toyo At2's.
I've always had squirm with my 2000 # camper and the At2's.
The most solid tire I've had was an M-55.
