Are my calculations wrong?

I think I goofed big time. After reading a lot about the Ecoboost, and having owned a 5th wheel with an F350 in the past, I decided to go with the smaller Ecoboost, and was impressed with the high towing figures. So, I got this nicely tricked-out truck, and much to my dismay, after reading many many posts here and on other forums, I am just worried silly that my truck is not up to snuff. I want desperately to be able to pull a 5ver, knowing the limitations with a short-bed (I had a Pullrite on the F350 and loved it), but it seems like this is not possible with the numbers I’ve computed. So, please help me out by checking my figures, and suggesting any possible solutions.
2013 Ecoboost, short-bed, FX4
3.73, Max Tow Package, 7650 GVR Package
GCWR=17,100
Max Loaded Trailer Weight=11,200
Rear GAWR=4050, Front GAWR=3750

I weighed the truck, loaded with fuel (36 gal), myself and passenger, supplies, but no hitch
Loaded weight of truck came to 6500
Unfortunately this was on a waste management co. scale that did not have a way to get rear axles.

If I add 200lb. to my truck weight (for a 5ver hitch), it comes to 6700. I subtracted that from the GCWR of 17,100 and got 10,400.
But then I subtracted the truck weight from the GVWR and got 950. I then divided that by .18 and got a final reading of 5277 lbs that I can safely tow.

Is this right? If so, it looks like a 5ver is out of the question because I doubt if there are any out there that would come in at that weight and be anything decent.
I pray that I am doing these calculations wrong. Even when I divided the 950 by .15 (for a regular trailer hitch), I still only have 6333 lbs to tow.
Something just seems terribly wrong and unfair to me. Don’t wanna whine because I do have this wonderful new truck, drives like a dream, getting over 17 mph, smooth ride, but I have just retired and was looking forward to getting about a 30 ft. 5ver or trailer and striking out cross-country. If these numbers are right, looks like I’ll have to settle for a hybrid or a pop-up!

Any suggestions would be helpful. And thanks for all the posts. I have been lurking on the forum for years but never felt I had enuf expertise to contribute anything useful. Maybe some day I can pay-back to all you folks who take the time to help those of us who are wandering around in towing la-la land!
  • if you didn't get the HD/Max payload package, you're going to be stuck with only the smallest 5th wheels out there.

    X2 to the statement from SkipnChar!

    It is necessary to order a Max/Max F150 to pull a 5er of any size with a F150. If you use to pull with a F350, I doubt even if you would have gotten the Max/Max you would fine the experience enjoyable. Even with a 5er , you will get to the point of the Tail wagging the dog!!
  • A few fifth wheel trailers will work for you although the makers like to sell the heavier models. Reading through your post, I was wondering if and when you would get to payload, which is the real place to start, not the television commercials touting 11,000 plus towing figures. Good thing you did some discovery before purchasing any trailer. Travel trailers can be a lot of fun too.
  • In order to tow a 5th wheel of any size you need to have ordered your truck with the HD Payload option (8200 lb. payload). YOu can still tow a 5th wheel but it will just need to be a smaller one than otherwise would be possible. Payload is the main thing to look at for 5th wheel towing regardless of WHAT size truck you are using. People are quick to point this out with half ton trucks but it is just as much a factor with 3/4 ton trucks but many just ignore it in that case.
    Good luck / Skip
