I'd be willing to bet the redesign of the Superduty will have a fully boxed frame. That says something. What was good in 1999 is now a step behind, and they will acknowledge that when they redesign it.

I will bet the pick up version might, but not the cab and chassis version. They will more than likely remain a C-channel frame from the bed on back just like the current GM 3500 and Ram 3800/4500/5500 cab and chassis are for easier up fitting. Most people think the whole F250/350 frame is C-channel, but it is not. Only the from the cab on back which I explained why earlier.

Both C-channel and fully boxed frames have their pros and cons, and one is not totally superior than the other in every aspect. One is just better than the other depending on the need of the customer. If you were going to put a flatbed or a welders bed on then you will want a C-channel frame for easier installation and you will not ruin the integrity of it as much as a fully boxed when you drill through it. If you just have a pickup bed, then fully boxed is the way to go.
