Ford's "2008 Expedition & Expedition XL" color glossy marketing material generically references the "Heavy Duty Trailer Tow Package" (does not mention the exact package identifier) on page 27. Page 26 has the information on "Trailer Towing Applications" (the max tow capacity per Exp when properly equipped).
Ford's "2008 RV & Trailer Towing Guide" color glossy marketing material specifically references the 536 package and its details in a table of all the Tow packages for all Ford vehicles on page 14. Page 15 indicates the need for this package to get tow capacity above 6000 lbs.
I know this since I made copies of those pages to show to the dealer when I was having a debate with the dealer on if I already had the 536 package (no) and then what I expected them to add when they agreed I did not already have it!
The Exp glossy was readily avail at my local dealer. The sales rep brought out the Trailer Towing guide when I asked questions that he could not answer. Thinking I was about to buy a used Exp from them (I eventually went elsewhere), the sales rep gave me a copy of the RV & Trailer Towing Guide and admitted they don't leave them laying out and only have a couple in the dealership for reference.

Thanks Dan, I finally found everything you discussed; but, had to do it on my own and with the help of dwsenko and this blog.
I'm gathering everything now to head back to the dealer and show them, including the service and parts department the real facts.
I bought this as a "program" vehicle with 20000 miles specifically to two the 9000. I was assured that was the case. The sales person showed me the web site. The owners manual was missing and I didn't realize it was only a 6000# tow when they got me a new one. I understand the sales persons mistake. In 2007 the Ford info certainly did not point toward the limited version.
What I am really ticked about is their service and parts department couldn't get, didn't really try to get the right information when I went back last month.
Should be fun this afternoon.

To Dswenko, Thanks for all your help. I finally negotiated a similar deal with the selling dealership for the 536 package.
As you know, the hitch receiver is rated for 9,200#, there are electric brake wires and receivers installed. The only addition was a larger radiator and cooler, your parts numbers.
It was labor extensive, so I would advise anyone that thought they got the heavy tow package and didn't try to get the labor done by the dealership. I thought replacing a radiator was simple, I"ve done older vehicles a lot. Ford Expedition requires removing the whole front clip and a bunch of surounding stuff. I put in my own 7 pin plug that was easy since the electric brake control wiring was already in place.
I think I was billed retail for the radiator and cooler, I'm working on that; but, my total parts only bill was 454.90. Brake controller and pin recepticle totalled around $160; but, I got a high end Brake controller to match one on my motorhome.
Longmont Ford, Longmont Colorado was my dealer that finally came around.

I did much of the same investigation so glad I could help. Sounds like you are where (or very near where) you want to be.
#24 of 68 What about rear end ratio?
Jun 27, 2008 (6:58 pm)
I believe to be rated at the full 9,000lbs you need the 3.73 gear ratio which is code 16 on the sticker on the driver side door sticker.
I hate how Ford has done a two tiered tow package. I almost bought an 07 Expedition that I thought was rated for 9,000lbs but didn't have the h/d tow package. I was about to sign the papers when I did one last walk around and noticed it didn't have a 7pin adapter. The sales person and sales manager were clueless. I used the manual to determine that no 7 pin connector means now HD tow package. Many of the 07 Expeditions I looked at lacked the h/d tow package. I finally found a used 07 EB with the h/d tow package and 3.73 gears and bought it. Tows great, much better than the 5.3 powered Suburban I traded in.

I had the same problem when trying to buy a used Explorer with its HD towing package. Most sales people had no interest in understanding that the light duty and Class III/IV hitches were different. When I forced the issue, stating that I ONLY was interested in the higher capacity hitch; they said that they would swap hitches. Starting in 2006 those hitches are welded, not bolted in place, as part of the frame; thus, a swap is impractical. Plus it wouldn't include the additional cooling capacity. I ended up buying a new Explorer elsewhere where the sales person actually listened to what I wanted.

Isn't it true however that in order to tow the 9,200# max with the HD towing package that you must use a weight distributing hitch? I didn't see any mention of it but thought it was worth mentioning. I could be wrong but I think that you still only get 6,000#'s with the HD tow unless you use the weight distributing hitch setup. Can someone help me out? I hope I'm wrong but that's how I read the sticker on the hitch that came with my 08 exp with HD trailer pack.

"Isn't it true however that in order to tow the 9,200# max with the HD towing package that you must use a weight distributing hitch?"
Yes that's true. I believe it's in the Expedition manual.
I've found out something else that may be usefull. There is a spark plug removal problem in the 5.4 Liter engine. The plugs have a long shank below the threads in a tight hole in the head going down to and open to the combustion chamber.
I called a lot of Ford mechanics and finally may have found the solution. On a Warm Engine, (most Ford Service reps said Cold engine, wrong) losen the spark plug 1/4 to 1/2 turn.
Then spray carb cleaner around the plug. It goes around the threads and breaks lose the carbon and crud build-up around the long shank of the plug.
I replaced my plugs using this procedure and everthing worked OK. You can hear the carb cleaner bubbling/sizzling, and the plugs came out fine. I used a magnet to pull them out and had to wiggle a couple of plugs. Still a pain and knuckle busting job; but, didn't break any plugs.
Champain makes a one piece plug, the stock plugs appear to be a bonded two piece shank. They are expensive and may not be necessary with the above procedure with a stock plug.

It may say that in a manual but in reality, that is not that simple. Most trailers weighing close to 9k lbs will require a w/d hitch because they will have tongue weight of 10-15% of total weight. 900-1350lbs of tongue weight is more than most pickups/SUVs can safely handle on the hitch ball. Boats are different because they usually have tongue weights of 5-10% of total weight which in most instances does not require a w/d hitch.
The key to towing with any vehicle is to make sure you don't overload the axles on the tow vehicle and having a trailer with proper weight distribution and the proper hitch and brake setup. I use my 07 Expedition to tow our 25' travel trailer that is around 6,000lbs loaded. I use a w/d hitch with a sway control device to safely tow the trailer. Used the same setup with my previous Suburban. Realistically, I would not tow 9,000lbs with any 1/2 ton truck. IMO, if your towing that much, you need a 3/4 ton. 80% of max tow rating is a more real world number.
