That level is off a bit and is actually dead level. I have one of those bubble levels I put in the refer to check level and it was spot on. The difference in height to get the bubble perfect is 1/4", the ball is at the right height, otherwise it will be nose high. Better to be a little nose down than nose high if you can't get it level.

9 links is too much for this, it will overload the front end, and be very difficult to disengage. It sits well at 8 Links, and still has a lot of tension with the jack fully extended with 7" of wood under it.

Sounds like you have it covered.

Fingers crossed, will know when I take it on the road again.

If 'tightening' the chain by a link or two doesn't have too much effect on the weight distribution (add additional dowforce to the front axle) you can tighten up by a link if you wish. You'll want to have the front and rear wheel well heights as close as possible to equal.

This is encouraging at least. The Service Manager drove my truck, his wife has a 15 EB and it exhibits the same steering problems. There was a problem with the IDS software, so they are unable to do anything about patching or updating until it gets resolved. They also need to order new brackets for their Hunter alignment heads, the ones they have don't fit the wheels on my truck, which are the factory chrome ones.

He is going to get those and have their alignment machine updated, so when that is done, will have me come back in, get it aligned again, and update the steering modules. Since the issue can be replicated, and the amount of force while driving varies a lot at a continuous speed, he thinks the updates may correct it.

Keeping fingers crossed.

Still waiting on a call from the dealer. I noticed that the issue has lessened a bit with the newer tires(OEM that it came with), but is still there. I haven't hooked up yet to take it for a ride since it would need to be gone through(the trailer) to secure everything for travel. We may go for one last outing this year, but haven't made any plans. With my back issues, and other things, just have not felt up to it.

The good news is the replacement driving lamp lenses are in.

Acdii finally saw what you have been describing in this thread in action today. I was out running some errands this morning and drove a few miles along side and behind a F150 (15-16 maybe)Screw 6.5 bed pulling a Jayco TT of maybe 26-27ft. The back end of the truck and the trailer was like floating slowly back and forth a inche almost constantly. The driver was just rolling along at 65-70mph like it wasn’t even happening but I could see him working the wheel a bit though. Just from what I could see he had the WD bars pulled up tight against the frame, the trailer was maybe slight high in the front, the rear of the truck looked to be at normal unloaded height. This appeared to be more a setup issue than anything else. Kinda wicked to see this happening at those speeds.

Heck I am working the wheel empty, so you can imagine what towing is like. Here is the weirdest part. I can hold the steering wheel rock steady with my hand planted on my thigh, and two fingers on the wheel, and the truck is moving left and right in the lane just as you described. In fact the dash starts flashing and dinging that I have my hands off the wheel. When weight is in the bed, it is even more apparent as you saw.

Hoping it is nothing more than an EPAS update to resolve.

Well, after two alignments, new tires, and new hitch, the verdict is... not much difference.

It was windy with 10-15 MPH cross winds gusts to 20 MPH, so not the best day to do a test drive on, but it was enough to determine that even with the hitch perfectly setup, verified by the scales, the truck just likes to corkscrew on rough roads, and it is going to do it no matter what I do.

Scaled it and my empty weight with me, a full tank and my usual stuff in it is.

With trailer and no WD from a previous weigh in, with me and the wife, half tank of gas, and the usual stuff we travel with.

Today with the trailer exactly the same, nothing added or removed, only difference is no wife with me, and a half tank of gas instead of full.

So I have 240 pound transferred forward and 240 pounds moved back. Can't get much better than that on the first try.

With the new tires and the second alignment it is driving almost as it did when I first got the truck, very little input to stay centered, but it still tends to wander when on a rough road, but the pull and hard set of the wheel is gone. When towing it stays straight on smooth roads, but on rough I can feel it corkscrew in the front, even though it appears to track straight, but the pop off is gone, probably due to the new hitch, so thats a plus. After driving an hour on the Interstate I feel that it has improved with everything done, but is no where near as stable as the 2014 was, which is a shame, only thing I can think is it has to do with the EPAS being too sensitive at center. I do know it does not have the same steering feel the 14 did with EPAS.

Overall though, the sway control works very well, the wind pushing against my left was forcing the truck left as I can see a slight right counter in the steering wheel, but except for strong gusts that would move the trailer, it held the lane very well. It will most likely be fine on a less windy day. Lets just say that the wind was so strong that I found myself going much faster than I should have when it was at my back. I gained 2 MPG heading home with the wind at my back.

I seem to be having similar towing issues. Did you ever solve the problem?
