Are you sure it's a Supercab or Crew Cab? The F-450 only comes in Crew cab...

 

It's a chassis cab. It comes in many different forms including reg cab and super cab. Unlike the pickup that only comes in crew cab.

 

Ok gotcha. I was like Ford is offering an F-450 in SC? Not that I would mind lol.

 

Before




After. 186" WB, 11' Bed, 15,500 lbs


This is what they look like.

 

To the OP, sorry I'm a bit late to the party and I'm sure it's too late, but I have an 11 350 and a 12 450. the 450 is CC, crew so 200" WB, so I think that's 184"c-a with stake body, 12'. Here is what I can tell you. CC has same drive train except rear which is a 4:30. In CC they detune engine so it doesn't carry the same 800/400 as pickups. I get 16 mpg with the pickup and I get 10 mpg with the 450 empty or full, doesn't matter. That said, I tend to agree with ford, I think you made the right call, just don't be surprised with the mileage.

 

10.6 MPG and the frame flex (Oscillation) was brutal. I had to have the Kelderman Air Suspension installed. Rides like a dream now.

 

Surprised you went with the 4:10 rear. what does that weigh with all you have on it?

 

That's an interesting Question.. The GVWR is rated @ 16,500 lbs.
But if you take the Front GAWR, it is rated @ 6,500 lbs. The Rear GAWR is rated @ 12,000 lbs. and if you add the two together it comes out to 18,500 lbs. I've got 6,120 lbs. on the front axle (leaving 380 lbs. to max Wt) and 9,300 lbs. on the rear axle (leaving 2,700 lbs. to max Wt) which in answer to your question is 15,420 lbs. which only leaves me with a total of 1,080 lbs. for the whole truck. To say the least.. My Rig is fully loaded.
The reason I went with the 4.10 gears is because Horse power is all used up by that much weight so the only thing remaining is torque. Torque loves low RPM's. The sad thing is the flimsy frame. Once the frame starts Oscillating it doesn't stop. In the drivers seat it's like riding a horse at full gallop with a very rapid forward to backward motion. you can't even talk because your body is being jerked back and forth.. The Air Suspension cushions the road and changes where the weight was placed on the frame..

 

That's interesting on the weak frame idea. I just have a 350srw long bed. This is the first long bed truck I've ever driven and it's very different than the shorter frame/WB trucks by a lot.

Even on my 350 CC I feel a lot of bounce, oscillation, and flex when I drive, whether I have a load or not. Things seem to handle smoother when I have a decent amount of weight over the rear axle but still, I'm pretty disappointed with the flex going on with what I believe to be the frame.

 

Here's an Interesting comparison of the difference in Frame design and material used. I used to have an 06 3500 W/ LBZ Duramax, 430 H.P, 800 Lb. Ft. Torque, 6 Speed Allison and Factory Turbo Brake. As you know the Chassis Cabs only come with 300-330 H.P and 660 Lb Ft of Torque. The only reason I had to upgrade is because I was 3,000 Lbs. over weight (14,200 lbs.) The Chevy 1 ton (same as my New Ford minus the extended Cab) Pulled like a big dog and I got 13.5 MPG. I miss the power but This fits my cargo much better. It's just a shame I had to spend $10,000 for the Kelderman Air Suspension to get it to ride like my Ole Chevy. The Ford C.C also has a 80 MPH limiter and does NOT have the Turbo Brake.. It's all Good now though.. You gotta do the best with what's available.

 

Here's another example of Ford Frame Engineering.. (Not..!)

 

Hey Guys, my new truck is being delivered on Jan 4th then going to Royal truck body for the body installation! Hopefully should have it by late Jan.

 

Hey croz, thanks for those vids but I don't buy into that kind of stuff. Twist and flex is not necessarily bad and arguably beneficial.

My issue is when the truck goes into a harmonic, rhythmic oscillation. Happens with an empty truck between 45-50mph and 70-75mph. The high speed one is really bad.

This rhythmic bounce feels like the frame is flexing up and down due to the large span between the axles vs. the short bed wheelbase.

The vehicle is smooth as silk with a trailer hitched along though....

 

I know about Smooth as Silk, my 06 Duramax 3500 84" CA Chassis Cab was that way with Bilsteins all the way around. Unfortunately I was 3000 lbs. over weight and went through 2 sets of rear springs but the ride was as good as my Denali XL. This 186" WB was my choice of the (2) 1 1/2" ton CC options and from what I hear from the Dodge owners are having the same rough ride but not many complaints about the oscillation (bobble).I think as far as commercial applications go (since the P/U's get a different motor tune and Turbo) the Chassis Cabs should get a stiffer Frame because some of us are loaded to the max "All the time" and could benefit from a solid platform. Flex in Pick-up frames might be acceptable. As nice as these Pick-ups are set-up I could see occasionally taking it out on the town. I can't see rolling my Weld Rig to Sizzlers just for the sake of it. My bed weighs 8000 lbs. and it is bolted as solid as possible to the frame every 2 feet so the flex isn't along the bed area. This Kelderman system defiantly solved the ride issue and all but cancelled out the bobble issue.

 

I don't know if OP knew this already or not but wanted to mention is for future googlers...

The big difference between the F350 and F450 (both chassis cabs and pickups) is that the front and rear suspensions both get upgraded. If you look at the towing guide/payload specs/axle choices, it should tell you exactly what you need to know. Figure out how much you need to haul and then look at the charts.

I recently upgraded my 09 SRW F350 CC LB to a 15 DRW F350 CC LB and considered the F450 pickup but ultimately didn't need to tow that much (my 40' GN trailer weighs ~16000 fully loaded and grosses 18000. I was towing at my limit with the 09. With the F450 (pickup) forcing you to 4.30 gears, I didn't want to take the hit in fuel economy as the 15 F350 with 2nd gen 6.7L was more than enough truck for my needs.

Enjoy your new truck! These things are awesome!
