So I was surfing eBay came across a old 1980s 4 door bronco centurion which gave me the idea f350 dully crew cab with a supercab welded to the back creating a large long cabin then welding 2 ft from a doner bed to make a ten ft bed
What kinda wheelbase would I need what is wheel base for a 8ft dually crew?

 

i would start with an f350 cab n chassis or f-super duty (f450) platform with the long wheelbase like my new to me truck,and build your setup off of this;



local co.extended this one.i dunno what its wheel base is.i didn't measure that yet.i run a tape from bumper to bumper though,and that was just shy of 25'.

 

What's the wheel base on that 200"ish

 

Centurion made an extended Crew Cab "Cowboy Cadillac" when they were still in business:





Shamelessly stolen from Audra and Traveler's site: 1995 Ford F350 4x4 Centurion Conversion Extended Crew

 

Oh and 450? Couldn't I just weld a extension on to the chassis

 

iv seen a couple of those over the years.^
if i was going to go through the trouble,id just go ahead and make it a full 6 door.same amount of work,so why not?

 

There used to be a 6 door mid '90s F-350 around here. It was on about 38" tires so it was huge. Painted bright orange too. Looked like the Great Pumpkin.

 

A 10'bed, super crew cab would be 214"wheel base.
Good luck turning.
A crew cab long bed is 168"

 

I'm trying to fathom why someone would need a truck like this. Hauling immigrants?

 

If You did a 10' bed then twin axles would be a sweet addition to it also.
Go big or go home brother!!

 

I Definetly don't NEED a truck like this but why the **** not lol

And I like the look of the supercab over 6 doors

 

 

What motor would u use 460 or 7.3!

 

I think rear steer would be a must in those beasts

 

Put a supercharged 460 to power the front wheels and all the electronics inside, a 7.3PSD to power both rear axles, (each engine getting their own set of dual tanks of course) and have a gap in between the cab and bed to allow for articulation. Makes perfect sense.
