Well so much for putting me on the ignore list.
I'm living on the edge.
I agree a C-channel is easier to clean than a boxed frame.
No, not easier to clean, but inherently easier to KEEP clean.
There is a difference. The simple design of an open-c simply doesnt collect junk as readily as a box section.
Dont know why you have such a hard time understanding that.
But claiming that rust is much worse on a boxed frame vs a c-channel is not simple fact.
never did I say rust was worse. What I did say is that rust becomes more of a problem on boxed frames, due to its design.
Most people don't clean their frames at all, regardless of whether they're c-channel or boxed.
More to my point of an open C being easier to keep clean.
I've seen boxed frames last just as long as c-channel ones...anecdotal on my part for sure...but since you're the one claiming to have a fact on your side, why don't you give me some actual statistics for how long a boxed 4runner frame lasts versus how long a Tacoma c-channel one lasts? I'm willing to bet that your own experience on the issue is anecdotal as well.
How about you provide some statistics to counter?
Im not going to spoon feed you.
Yes, but my opinion has confirmation of sorts in that Ford now uses a fully boxed frame for the Super Duty, as do most other pickup's and BOF SUV's...I suppose there must be some reason why that frame type is so prevalent within the 4x4 vehicle segment.
Your opinion carries as much weight as any other member on this forum.
That said, yes, Ford has pushed to a fully boxed frame. And until you provide proof of anything contrary, Ill continue to assume it is due to cost and marketing.
But isn't it funny that they don't offer a fully boxed frame on F450 and up?
How common is "common?" Are you basing this off a few internet threads or do you actually have some NHTSA TSB's and recalls to prove your point? Were these vehicles stock or over GVWR? Again, my anecdotal side here, but I've seen plenty of 10 year old FJ's, both stock and modified, on the road and I haven't seen any common issues with that frame failure.
Again, I wont spoon feed you..
Again, how common is "common?" FWIW, Toyota was a company that was
noted for having frame rot issues, and all of those affected vehicles (Tacoma, Tundra, Sequoia) had C-channel frames:

That seems to stand in direct contradiction to your conventional wisdom on the merits of c-channel frame construction. In my
opinion, the quality of construction and finish at the factory has more to do with premature rust issues than does the type of frame used.
Huh, a few post back you were preaching that it was all DESIGN related.
Yes, the Toyota chassis fiasco was an open C based chassis. But if you actually do some research, you will find it had nothing to do with the design or fit and finish. It was a "simple" manufacturing problem related to the steel used.
The entire chassis was effected, and if you've seen the problem first hand youd know that the frame rotted in such a way that the chassis actually starts to de-laminate as rust takes hold.
Toyota has issued similar recalls in the past due to bad steel. One is a significant lead spring recall.
