Do any of you know if I need to order the entire Trailer camera and TPMS kit again for my new 2020 F450 Limited.? I already Have the kit installer on my RV from my 2017 F350 and I'm afraid if I don't order the kit,that the won't be prepped for it. The kit was around $800. I'm thinking I should just order it to be safe then sell it with my 2017 F350 Platinum DRW white.

Mine advantage of a push rod engine while at the same time a disadvantage.
you will get good low rpm power and torque but you are not going to be able to Sustain the hp/tq to rpm ratio as you pass the push rod performance barrier which normally is 3500 to 4000. Pushing beyond that will accelerate wear and bend rods.
the first thought I had when I heard that the 7.3 was a push rod gas motor was that some back yard joe is going to convert that thing to run diesel.

Where do you people come up with this tripe??
Valves could give a rat's *** how they're activated.....a pushrod motor does not magically make "good low end power."
If you want to state the advantages of OHC/DOHC it is in the ability to reliably rev higher ....Ford never utilized OHC advantages in the 2 valve mod motors.
Pushrods make more low end is about as dumb as saying diesels make more torque.....(hint, turbo diesels make more torque.)
And I know I'm going to regret this, but what rods are bending above 3500-4000 RPM??

Why is everyone saying the power is low compared to a diesel.
The fact is, it's not.
The power is low compared to a TURBO diesel.
A N/A diesel is an absolute dog CID to CID (if there are any even available any longer)
Granted, the PSD is still the absolute beast in a Super Duty......but not because it's a diesel alone.
And while I loved and miss my '12 PSD, I do not miss the maintenance and having to hold my breath once the warranty expired.

Talking 6.9 idi vs 429
7.3 idi vs 460
And any other similar normally aspirated diesel vs gas.
Any N/A diesel is a turd compared to the same displacement gasser.
Heck, even modern forced induction gassers have more power than "longer stroke" turbo diesels. (Just compare the 150 lineup)

"It’s a gasoline based engine, it has compression limitations, and for low RPM, or any RPM, The torque numbers are going to be less than half of the diesel."
It doesn't have 1/2 the torque because it's "gasoline based."
It has 1/2 the torque because it's N/A.

Nah....even if the ratings were close, the shorter stroke gas motors destroyed the long stroke diesels in performance.

But that's not what you wrote....in case you forgot:

Careful. Don't post too many facts to a diesel apologist.

Obviously adding a turbo would make more power on a gas engine, but a diesel is a different animal.
Look at it this way, a gasoline engine is more like a wood stove. You have to manage the damper to burn the wood the most efficiently. Too much fuel, or too much boost and the fire will suffer.
A diesel is like a bonfire that doesn’t care. Just keep tossing in wood, and it will burn all you can throw.
More fuel, more boost, more power.
The 6.4L is a perfect example. You can simply add a tuner which adds fuel, changes and expands the fuel pulse which builds more boost.almost 50 lbs in that engine.. that can double the power to almost 1,200 lbs of torque.
It doesn’t work that way with gas.

What's funny is if CAFE applied to HD's we might have an EcoBoost version of a gasser in the Super Duty.
Which admittedly might be silly since the better economy numbers would be with an empty load.
The 3.5/2.7 EB is the perfect example....decent economy empty but pails in comparison to the 3.0PSD working.
But empty or fully loaded, both gassers destroy the diesel performance wise.

If that were possible, why isn’t it available in the big 3 trucks?
Why can’t I buy a new Peterbilt 389 with a gas engine?
Simply put to those gasoline apologists who don’t understand physics, there are more BTU available in Diesel.

The only reason a diesel can out perform a gasser is with forced induction.
And they absolutely care.
What's hilarious is EVERY bombed diesel with anything more than a mild tune, regardless of brand, is a POS when it comes to HEAVY work.
The EGT's start melting things when pulling HEAVY toyhaulers up major grades.....they learn to swallow their pride and revert to the stock tune when pulling.

Explanation in prior post. Well.. Show me a gasoline engine that you can buy that will make 1,000 lbs of torque?
If that were possible, why isn’t it available in the big 3 trucks?
Why can’t I buy a new Peterbilt 389 with a gas engine?

I've never seen anyone twist crap more than you.
The reason you don't see 1000 foot pound gassers is simple.....fuel economy.
A properly built 7L forced induction motor is more than capable of making that much power.....
But 2-3 MPG would not be acceptable in any production vehicle.
BTU is not the only factor here.
Spark ignition vs compression ignition is a factor...
Look, I already said the PSD is the only choice for the current Super Duty if ultimate power is the need/want.
I only commented on the ignorant comment that the 7.3L is down on power compared to a diesel because it's "gasoline based."

(EDIT) Is 950# close enough for you???
