Jeanie and I have turned the page on the truck to haul our 2020 N* Laredo SC.
This week we bought a 2020 Ford F-350 XLT SRW, SB, Super Cab, 148" WB, 7.3L gas V-8, 10 speed automatic pickup.
Our decision to buy a gas truck is predicated on the super high price of diesel fuel in CA, and the $10K diesel penalty when you buy it new.
PLUS,
Jeanie no longer wants to drive and shift the NV5600, easy as it is, so I do almost all the driving.
AND,
This Gen II Cummins (2001-2002 High Output) is THE loudest of the breed.
The F-350 gas is very quiet so Jeanie and I can talk during long trips, and she can now do a lot of the driving on long trips.
I may get 35 inch tires when the 33.2's wear out, and add a Tru Trac locker in front, but that's about it. No lift. It's high enough as is.
Besides, we'll keep the '01 Cummins for the really hairy trails and the approaching armageddon. The F-350 will be the culturally acceptable rig, not the gnarly mud rat.
This one has the jobber electrical package with lots of extra switches for whatever and an AC inverter to run electrical equipment off the truck. The dual batteries and huge alternator capacity also come with the ambulance and emergency equipment trucks to keep the lights on.
All current diesels have 2 batteries. Almost all gas trucks have only one battery.
This new 7.3L Ford gas V-8 is a stand alone engine in the industry. Since the slow demise of the V-10, nothing can touch the HP and TQ this thing puts out. The same engine and trans is used all the way up to F-650's.
The only thing it does not have is a rear anti-sway bar to make it truck camper certified. But you could not get the high spring rating and an anti-sway bar together.
Below are the specs for our new truck. I am overwhelmed at how overbuilt this truck happens to be.
It was spec'd out to be a tractor to haul a 5th wheel.
2020 Ford F-350 XLT 4WD SB super cab, 147 WB.
Engine: gas V-8: 7.3L (445 cu. in)
cast iron block, aluminum heads, pushrods
bore: 4.22 inches
stroke: 3.98 inches (unusually square for a Ford)
HP: 430-450 @ 5,500 rpm depending on the model
TQ: 475 # ft. @ 4K rpm
It's around 600 pounds and 525 pound feet of torque lighter than the current 6.7L diesel V-8
dual 750 cca batteries
dual alternators with a total of 397 amps
Transmission: H.D. TorqShift automatic 10 speed (10R140) which is used with the gas engine in trucks up to F-650
Gears 8, 9, and 10 are overdrive gears. How may autos do you know of that have an overdrive @ .63:1?
First gear is one of the lowest of any automatic, made for trailer starting and hauling heavy loads.
This THE widest gear ratio automatic transmission I've ever run into: 4.615 to .632
Plus the reverse is 4.7:1
First 4.615:1
Second 2.919:1
Third 2.132:1
Fourth 1.773:1
Fifth 1.519:1
Sixth 1.277:1
Seventh 1:01
Eighth 0.851:1
Ninth 0.687:1
10th 0.632:1
Reverse -4.695:1
transfer case ratio: 1:1 and 2.64:1
52.39:1 creepy crawl ratio with 4.30 gears and the auto’s 4.615:1 low gear
4.615 x 2.64 x 4.30
8 x18 wheels
275/70R 18E A/T 33.2 inch diameter tires with a 3640 pound maximum load rating
axle ratio: 4.30:1
front axle Ford, made in-house D-60 style, 35 spline open diff, 28 spline pinion, 4800 pound maximum load rating, which is fine with a much lighter engine up front.
electric locking rear Dana M275 differential with 1.53 inch, 36 spline axle shafts. Ring gear diameter: 10.8 inches.
It is stronger than my Dana 80/35 spline in my Dodge. The case looks like something from an army truck.
Ring gear diameter: 10.8 inches
auto front locking hubs
skid plates
aluminum bed and cab
6,653, 6,648, 6,798 or 7,245 pound curb weight depending on whose stats you believe
skid plates
payload: 4610 (base) or 4580 or 4320 or 4066 pounds depending
It has 4 thick leaves in the rear pack and a single upper secondary spring.
The GVWR is 11,300 pounds, mostly to do with the single rear tire 3640 pound weight E rating.
the DRW F-350 with two more tires and no significant drive line or suspension changes has a 14,000 pound GVWR mostly to do with tire rating
Class V trailer tow rating: 20K pounds
max 5th/gooseneck tow weight rating: GCWR: 28K pounds
it has the 5th wheel hitch prep across the frame under the bed further stiffening the truck’s frame
I'm expecting the actual net weight of the new lashup to go from the Dodge's 10,600 pounds to under 10K pounds, well under the GVWR.
