Noise While Pulling 5th Wheel
I pull a 5th-wheel RV with my F-250 Super Duty extended cab truck. I have the Triton 5.4 Litre engine and a 4.10 rear axle. The 5th-wheel RV dry weight is 9,150 pounds - when loaded it is about 9,500 pounds. The truck is rated to pull 9,600 pounds.
I'm hearing a noise and feeling a vibration under the drive train "hump" in the cab of the truck. It sounds like a transmission problem. However, the transmission isn't slipping, the transmission fluid is still a bright clear red and there isn't a "burnt" smell to the transmission fluid.
In addition, the floorboard below the passenger seat gets hot while pulling the 5th-wheel.
I've had the truck in to the shop twice (it's still under warranty) and tried to explain this to the mechanics. They hook it up to a computer and tell me nothing is wrong. The noise being made is definitely wrong and I can't figure it out.
Does anyone have any ideas on what I might suggest to the mechanics at the dealership where I bought my truck?
Thanks.

I don't believe it is unusual to experience extra heat in the floorboard area when towing heavy loads.

When?
When accelerating?
Decelerating?
What gear?
All of them?
While cruising too?
Only with the trailer attached?
What RPM does it start at?
etc. etc.
Lots of information helps all of us help you!
BTW, your exhaust runs underneath your passenger side seat so as 4x4x4x4 said, it is probably normal since yer towing a heavy load.
And since we're on the subject of heavy loads...what does your rig (complete with stuff, gas & trailer) weigh in at...exactly?

The rig weighs 9,150 lbs dry weight. We add about 500 pounds of weight with our "stuff." I don't fill the fresh water tank while pulling and never pull with the gray or black water tanks full to save on weight.
The dealership where I bought the truck said I shouldn't have any trouble pulling up to 10,000 pounds with the truck, so it shouldn't be a problem.
The noise only happens when I'm pulling the rig and only happens after a stop. Sometimes I'll pull forward after stopping, or turn left or right and get the noise. It never happens while cruising, whether going up or down hills, or on a flat stretch.
Gee...thanks for answering me. I love my Ford truck and my 5th wheel. We take it camping at any time of the year. The best times are when my boys and I are using it for "Deer Camp."

The catalytic converter is under the passenger's seat/floorboard. My truck also gets hot there when towing. I'd say this is normal.
As for the noise, I'd recommend checking the transmission mounts. Sounds like maybe one is loose and letting the tranny move when you apply power.
