1300-1400 rpm vibration anyone else

[rvdb]

I asked this in driveline section with no reponse & it's at the dealership for its 3rd visit with Ford MoCo involved. Hi, First off I am new to the site & appreciate any input, I picked up a 2012 F350, 4x4 CC, LB, a month ago and I am in need of help, I searched the site, asked questions on other threads with no luck.
I have a vibration at 1300-1400 RPM roughly in between 35 to 45 miles an hour, I am guessing its driveline related due to how the vibration comes about.
Ford replaced the drive shaft and balanced the exhaust and checked/balanced the tires.
The problem still persist, I was sent out the door per Ford. I have 800 miles on it and really like the truck however I feel this will lead to premature wear of components not to mention when I break it in & start towing 12k lbs.
Questions; has anyone dealt with this, does it get worse or stay the same?
I am very disappointed in this product at the moment, and I am frustrated, thanks for your time.

is the vibration in the seat or the steering wheel?

It comes through the seat, however it is not easily pinpointed it feels like it comes through the entire truck, I did notice last weekend I put 150 miles on it and the vibration fluctuated, It felt worse a couple of times. Thanks for your time, I feel like any info I can give the dealership/Ford Motor Company would help get this resolved quicker.

does it shake if you throttle the engine up in neutral while sitting still?

This is why these types of sites are great, poormanscat, I tried numerous things and never thought of that, I will ask the tech on Monday, thanks for the question/suggestion.

My F350 DRW is doing the same thing and is getting worse. Seems it does it between 1000 - 2000 rpm. Its a moan with a slight vibration and is very annoying. I feel it through the throttle pedal more. Any Clue? Does this in gear and in park.

Well Ford still has the truck, it does not vibrate in neutral.
I stopped by yesterday & they had a machine Connected to it that senses the vibrations and the noises as they are driving it. So far they can't pinpoint it. It's disappointing a two month old truck that's been with Ford for one of them.

I started noticing this week mine doing the same thing. I bought it used with 30k and have had it 1 month. It's almost like your going over a washboarded gravel road then it goes away once you speed up. But doesnt do it every time.

F350CRAZY, no clues till yesterday, Ford called and they are going to replace my trans, they found it via the vibration/sound unit they had it connected to the truck for a few days while they drove it moving clips till they pinned it down. I hope this is true and correct. They said they found two different issues. I will wait and see, I will let you know I went & drove a like 2012 yesterday and I was able to get it to do the same thing quickly, without starting a storm I really wonder if Ford received a bad batch of torque converters or transmissions.

RTRBURN, I drive like an old man most of the time & the area I live around keeps me in the 35-50 mph zone so it comes around at every run up to speed from a stop.
If I throttle through it you can easily miss it, however at $4.39 a gallon and residential areas I was continuously feeling it which is why I am here. If it goes "through the truck"? it might be similar. Good luck
