No disrespect intended, but as a former owner of a Navigator, you are overloaded. There is no fix other than to get a proper tow vehicle or a smaller trailer. There are many that will tell you that you are fine, cuz it pulls just fine, but not the case from my experiences. Let us know how safe you feel towing up or down a large hill on a freeway or maintaining control in high winds or better yet stopping in a hurry.

The Navigator is designed to be a "luxury SUV". The suspension and air ride are meant for the ride vs towing. The only thing my Navigator towed without issue was a 25' Wellcraft (boat). Best of luck to you.

I would pick up the L bracket up one hole or put another washer in the hitch to take some weight off the back axle and put some one the front as in the owners manual.

I was getting a bit of proposing myself. Even with a 3/4 ton. Today we traveled a bit more that 300 miles after I made some adjustments this morning. I added a washer to my equalizer 4 point and moved all heavy items I had stored in the outside compartments to the nose of the trailer. Leaving the the lighter items in the rear. Much better now. Wasn't bad before, but better now.

I greatly appreciate it.
Yeah I think tow capacity doesn't matter in this case.

I'm sure your payload sticker is in the 1500-1600 someodd lb range.

Payload is the measure of weight straight down on a vehicle. If the advertised tongue weight is 850, it's likely to be more like 950 in reality, maybe even over 1000. Then of course you deduct the weight of the hitch itself, and you and passengers and other gear... and you start getting close fast.

The smooth ride suspensions just aren't designed to "control" the weight when coupled with weight moving side to side way behind the vehicle. Your hitch point becomes a lever point that is exerted upon in many different directions at once..... think about it for a second.

When the rear of the trailer moves, yaws, jars, or rolls... or some combination usually.... the trailer then exerts all of that weight and energy of the trailer moving plus the tongue weight to a single side of your rear suspension.... it lifts one side and compresses the other in a roll. It pulls side to side in a yaw, and it pushes and pulls up and down in porpoise. With the current state of highways, it's almost unavoidable.

Consider all of the weight of the trailer leaning to one side in a roll, it's literally exerting that weight to the hitch.

When the suspension can't return the trailer, the weight lingers and the rear of the truck starts to track that way.... but of course, the trailers suspension will eventually return the trailer, but when it does, the truck is lagging behind, and the trailer sort of oscillates to the other side to some degree. This oscillation starts the sway, which can increase as the two fight each other for who's in charge.

The job of the suspension is to force the trailer back in line, to resist and return. And this requires a stiff suspension.

Add in a nose high truck, and you got yourself some white knuckles as the steer tires can float, especially when the trailer dips nose down.

I have a hard time believing they let you drive off like this. That's a shame.
I'd even be *slightly* skeptical of 3/4 ton truck with this trailer. I'd feel very comfy in a 1 ton.

Sorry you're having to go through this, it can be a hassle for you.

If your Navigator is a 4 x 4 driving it in "4 x 2 mode" is not going to give you the 400# or so that you lose in tow rating, because of the extra weight of the 4 x 4.

2x4 often do have more towing and more importantly, payload capacity. But you are right in that driving a 4x4 in 2x4 makes no difference.

I think the air ride is making it difficult to set up the WD hitch properly because you cannot go by fender height. Since the suspension attempts to restore ride height your only option is to do a few 3 pass weights on a scale so you can find out exactly how much tongue weight it has and how much weight transfer you have.

Might take 3 sets of 3 passes each to get it dialed in. Read the sticky at the top of this section on weighing to learn how to get accurate weights and how to read them.
