Is it true the cab is designed to be taken off?
It is true that that the 2008 Super Duty truck cabs were designed to be removed for servicing or you could say that they are more "service friendly." Separating the cab from the chassis is simply the reverse process as mating the two during production and you might be surprised how few items actually need to be disconnected or removed and drained. Since the beginning of the 6.0L production and the disasters we encountered in the beginning Ford was watching (from a distance) technicians removing the cabs because it allowed us unobstructed access to the entire engine making many procedures easier, safer and more comfortable. To this day, Ford Motor Company does not endorse cab removal on any pre-2008 trucks. While you can work on this engine with the cab on there are many things that in my opinion cannot be performed properly simply because of access. Try pre-torquing injector fuel lines or the exhaust pipes for example.
When Ford designed the new Super Duty they realized that the 6.4L engine was going to present some difficulties where servicing is concerned and set out to make cab removal the preferred method for performing most major repairs. In doing so, they cleaned up harness connections, utilized quick disconnect fittings on radiator hoses and so on. Keep in mind that dis-assembly is quicker than re-assembly because recharging the A/C, purging the cooling systems, purging the fuel system for example require more time than the act of "draining." We can do other things while the coolant is draining.
Why would it take 6.7 hours to do?
Think about the time, halving it is about 3.3 hours. You need to drain the coolant, drain the power steering/brake booster, discharge the Air Conditioning, remove those troublesome body bolts, attach and secure the cab to a hoist, disconnect wiring harnesses, A/C lines, hoses, brake cable, transmission and transfer case linkages, remove the master cylinder, remove batteries and battery trays... The battery trays were well conceived by the way as they actually incorporate the washer and coolant reservoirs. I have no doubt that there are technicians who can beat the book time but there are some guys who are truly gifted with dexterity and then there are those who rip and tear through a job. Many of us are more concerned with doing it right therefore watching the clock is not always in everyones best interest but that is a whole different topic for another Forum.
Remember, the guy that rushes through the job is more likely to be the one to leave the steering shaft bolt loose...
