I just bought a 2015 Expedition King Ranch with 24k miles on it and has a payload of 1365. I got it because my family owns a travel trailer and my dad's 2012 F-150 Platinum (3.55 axle and 1205 payload) is the only vehicle that we have to tow it and it's racking up some miles. So I wanted this to help tow the trailer and save him some miles. The travel trailer is 6235 dry (about 6600 packed), and the hitch is 675 (almost 700 packed). We have the EAZ-Lift weight distributing hitch that allows 1,000# for the hitch. Over the weekend, we decided to hook the trailer up to my King Ranch and see how it pulled. I'd like to pull it on our next camping trip. But the back end sagged so badly that it scared the heck out of me. It looked like my rear tires could hit the top of the tire well and my front end was so high and light that I would fish tail in the front and bounce. Totally not safe. I've read some other threads and saw where people said to go to Etis and find out if it's got self leveling load suspension. I went and entered my info and all I could get was I have a 3.31 axle. There is a section for more info but when I click on the plus sign to expand it, it doesn't expand. So I don't know what the suspension is but I'd say it's standard factory and not the load leveling. My dad seems to think that because his truck's hitch ball is 2" higher than mine, if we just get me a new hitch with the adjustable shank to raise it up, that will work because it would start out more even. I still think it will sag because weight is weight. I did see another thread where people suggested Nivomat shocks. I have tried to google and found some info but cannot find where to buy them. And when I would go to Pepboys or Autozone, etc., and enter my car info, no one gave me the option of buying Nivomat. And, like I said, I didn't find a lot of info on google. Can I get these for a 2015? Are they only available through a Ford dealer? Is there something else I should be looking at like air bags for the rear like my dad has on his truck? Am I just completely hosed by the dealer and can't pull this trailer? I am sick to my stomach to think that I just made this big of a purchase to tow the trailer and I might not be able to. I thought I did my research to know that the vehicle would definitely pull within the trailers weight and the payload would definitely take the hitch and us both in the SUV. I don't know what to do so any advice would be appreciated. Thanks!

1st you want to take the ex[y and the trailer to a level parking lot. Un-hitch the trailer and make sure it is level Then measure from the ground to the top of the coupler on the hitch.

Then measure the hitch head from the ground to the top of the ball Ideal is those two measurements should be about the same.

Then hitch up the trailer to the expy. Then adjust the spring bars so that you get the same measurement again This is an easy simply way to get in the ball park You may need to do some fine tuning after this.

Go to this page and put in your VIN and you can download the build sheet for your truck: https://www.etis.ford.com/vehicleRe...aykbgCvkAS_vVeJParW2MUx_3SMg93ECJ.eccvas1900i This should take you the exact spot. Try it again.


Thanks for the link. That is where I have been going. I don't know if the site doesn't like Macintosh's and maybe it only works on Windows machines, but once I enter the VIN, it pulls up a 2 column Vehicle Summary page. On the top right, it gives me a list of Primary Features and then under that is Minor Features and it only list the interior color. Below it it says to click to get more features, but when I click on the plus, it doesn't do anything. If you want to try it to see if it's a MAC/PC thing, I would appreciate it. We don't own a PC to try. My vin is 1FMJU1JT7FEF07038. This is a sreenshot of what I see when I try to look at it.Screen Shot 2017-09-12 at 11.58.54 AM.png
