RE: Help me avoid mistake!
Lincster I completely agree a 41 is too much for any SRW. I don't tow at 75, 65 max and have been in 35 knot 90 degree crosswinds for hours across South Dakota with mine and it was comfortable. The OP's choices are 36' units. YRMV

RE: Help me avoid mistake!
I beg to differ with the dually crowd. My SRW 350 towed my Fuzion 322 and my current Cyclone 2812 with 0 drama. This is up and down the Sierras and across the country. Larger than a 36' yes I agree but a SRW one ton especially a new one from any of the three will do just fine.
The axle ratio is a non issue as well, the ratios are suited nicely.

RE: Viair system with airbags anyone??
Aren't the bags supposed to be independent to keep the pressure's balanced on a side to side load like a corner?

RE: Ford's answers to the NHTSA 6.7 Investigation
It actually would take 2 filters, one return low pressure from the cam cavity and one on the discharge high pressure.

RE: Ford's answers to the NHTSA 6.7 Investigation
News,
Ford's guidance to techs is if the engine is even started post WIF or improper fueling event the entire fuel system is replaced except the LP lines and tank but those must be cleaned.

RE: 2013 Raptor 300MP
It is an excellent match in my experience. My personal limits are over 36' is dually territory. I towed a Fuzion 322 (virtual twin to the 300 MP, nice choice btw) with a SRW Ford all over the Sierras without any Post Traumatic Stress Disorder to show for it.

RE: Ford's answers to the NHTSA 6.7 Investigation
No disrespect but Niner you missed a golden opportunity to add to the knowledge base here, that metal slag in the Volume Control Valve bore should have been sent to an oil sample lab for material analysis to identify the metals.
Thermal issues for the fuel must be non trivial here, look at the water/ fuel coolers both VW and Ford (I'M sure GM is doing the same thing) are using. Ford feeds this direct from the Secondary Radiator with a 113 F thermostat. Anybody know if VW has a split cooling system like Ford?

RE: Two Low Milage 7.3 PSD...
Owning an 01 for 10 years, great truck, hell a trusted friend. Great info here, a couple of clarifications. The powder metal rods are fine for stock or low power chips. The change to Motorcraft Gold coolant in 02 iirc is what eliminated the Coolant additive. If you change to that coolant none of them need the additive.
Which truck do you like best? If they are autos a trip to a trusted tranny shop for peek in the pan is money well spent as it is the weak link.

RE: Read The New 1 Ton Truck Test From Motor Trend
If Cummins is running on Emissions credits why were they advertising 2010 compliance back when the engine came out? The standards were set back then at the same levels as today so what changed to cause them to be on life support?

RE: LT tires, or Trailer tires... Whats best ?
I think the weight being referred to on the tag is the amount of empty weight on the axles. It's not the GAWR. Add the Axle and Tongue weights and subtract from 13,000 and you have the Cargo Capacity.

RE: Price Check on 34' Attitude 5th Wheel TH
Best RV is great for pricing but, marginal at best after they have your money. Refused to let me leave my Fuzion for walk thru items. I had to have an appointment did not matter I was 110 miles from them. Of course I picked it up on a Sat. and of course they insisted on the check before we inspected so they could get to the bank before it closed. Bring your own gas to check the gen. They don't have any on site.
Dig your heels in and that gap between loaded and stock will close.
You be the judge.

RE: Rubicon Run
The entrance for the East side is off of 89 between Tahoma and Chambers Landing, it's marked IIRC. No camping just staging facilities on that side. Headed west to Rubicon Springs is doable but climbing out of the Springs there could be some winching required for a Rhino. As somebody else mentioned, there will be blood as far as body parts go. Have fun

RE: Ford's answers to the NHTSA 6.7 Investigation
Perhaps the CP3 does not use a DLC cam face. The lower pressure is surely a factor as well. The impact from a floating roller for what ever reason could also deflect the base metal of the cam and doom the DLC to flaking or failure of the adhesion to the cam. I would imagine any debris in this equation would prove fatal to the pump.

RE: Ford's answers to the NHTSA 6.7 Investigation
Hi all,
Here's a part of the Fuel System explanation from the Coffee Table book:
FUEL SYSTEM
At key on, the fuel pump within the Diesel Fuel Conditioning Module (DFCM) is turned on and the low pressure fuel
system is pressurized. If the engine is not started, the pump runs for up to 30 seconds. The PCM obtains information from
the Ambient Air Temperature (AAT), Engine Coolant Temperature (ETC) , Engine Oil Temperature (EOT) , and Fuel Rail
Temperature (FRT) sensors for fuel delivery calculations. The Volume Control Valve (VCV) and Pressure Control Valve
(PCV) are open.
During engine cranking the PCM identifies Top Dead Center (TDC) within approximately 120 degrees of crankshaft
rotation and PCV is closing, allowing fuel pressure in the rail to achieve the calibrated value. This allows the engine to
start very quickly.
Once the Fuel Rail Pressure (FRP) sensor detects the required fuel pressure, the PCM begins fuel injection operation to
meet the desired idle RPM based upon the temperature sensors and engine load. During this initial start up mode, the
high pressure fuel system is run in PCV mode for a calibrated amount of time. The VCV is set to a specified point while
PCV is duty cycled to meet the desired fuel rail pressure.
The high pressure fuel system operates in PCV mode until a calibrated fuel temperature and time is achieved.
In VCV mode the fuel volume entering the high pressure fuel pump is adjusted by the VCV to meet the required fuel rail
pressure while still being trimmed by the PCV. VCV mode is a more efficient operating mode because only the amount of
fuel required for combustion is being compressed by the pump and sent to the fuel rails.
During acceleration, the VCV and PCV are commanded to meet the driver’s demand (accelerator pedal input/engine
load). The PCM’s commands to the VCV and PCV are based upon: FRT, ECT, EOT, ATT, engine load, and regeneration
state.
On deceleration, the VCV is closed and the PCV is opening to max position to reduce fuel pressure. When RPM is
approaching the desired idle speed, the VCV begins to open to prepare for injector usage.
During regeneration, the left side injectors perform post injection. The right side injectors do not provide fuel for
regeneration because right side cylinders supply exhaust gas to the EGR valve and EGR cooler.
Under certain conditions, like battery disconnect and fuel system reset, the fuel system operates in Adaptive PCV (APCV)
mode on the first start. In the APVC mode, the PCM is learning the duty cycle needed for the PCV to achieve the desired
fuel pressure.
I have always wondered if the Volume Control Valve has been a piece of the puzzle. Also don't forget that these engines can be spinning 3500- 4000 rpm in Engine Brake mode with the VCV closed on a good downhill while towing.
To answer a few on going questions,
The HPFP is gear timed to injection events for pressure stability.
There is an area in the left fuel rail which acts as a damper for pulses. Left rail feeds the right rail.
The inlet fuel pressure is regulated to 100 psi from the DFCM pump.
From day one I felt the corrosion shown in some pictures of the fuel system parts was caused by the acids in Bio firing off the mild steel of the fasteners etc. I wonder if some of the deposits in the rails shown by Ford are actually the lacquer discussed in some of the papers and not corrosion.
I would love to see pictures of Ricatic's pump carnage, I imagine he has something which is keeping him from posting them.
As far as counting the odds, imagine what the odds are on a husband and wife both being diagnosed with MS 12 years apart. A virtual Father of Modern Neurology at the Mayo in Rochester guessed in the billions, but it is my reality. Pardon me if I hesitate to gamble.
I really have had my truck be trouble free and like it alot, but a 10-15k hit means no meds for a while at 1208.00 a month, not pretty. The fact that the failures are so rare is even more frustrating as to why Ford won't belly up to the bar.
This is the Achilles heel for these trucks.

RE: Ford's answers to the NHTSA 6.7 Investigation
Another item for the cavitation discussion is the fact the Volume Control Valve is on the inlet side of the CP4.

RE: Safety First. Need Help
I own the same unit as she is looking at, to get it to 14K is going to require a lot of cargo in the parking area which is going to lower the pin. The advertised pin of about 1900 seems to be accurate.
I towed mine all thru Midwest and Black Hills/ Yellowstone with full water and fuel, no toys, just about the worst combination for pin wt, using an F250 with 8800 GVW that went 7900 with 2 people and fuel, hitch, Golden Retriever etc. 45 psi in the bags and 80 psi in the Michelins and all was well. The 7.3 was stock except for exhaust and gauges, the tranny was built with a Precision Tq Converter (excellent unit).
A newer D/A combo in a long bed would do even better, Lucky Cosmo have fun and you'll like the Road Warrior pulled by your truck, they are very well matched.
