Yes, yours may be rated for that, but Ford has to engineer for the people that do not pay much attention to ratings. ie the guy with a load of gravel in the bed and a bobcat on a trailer behind his F-250. It is easier to overload a pick-up and think that it should be able to handle it. I have seen 5200 pounds of pea rock in a short bed F-150 SupCab before and nothing broke.
The Excursion is only rated to two 11K. (w/the PSD or V10 w/4.30s)
The Excursion's rear part of the frame is "weaker" than its pickup brethren but only because the body structure is so much stiffer compared to a pickup box. Made as stiff and there would be parts of the body structure that would yield under certain conditions.
i see my frame getting rusty as heck, just like my hitch.
nothing that could be called off roading done with it and owned it since new....
and i too am no expert.
Unless things have change I believe that F250 and F350 have the same chassis. Its suspension, brakes, other minor things that makes the difference in the ratings.
Its not cost effective to build to complete different frames for the same bodied truck.
I know thats the way dodge does it for a fact. I can not imagine ford being that dumb. Anyway. I am pretty sure that it is an slightly modified F250 chassis.
Lighter springs for smooth ride. and relocated cross members to make room for the X body.
Not an expert on fords, damn close on dodge though
It seems like a bunch of people aruging about the same thing. Last I cared about this issue, I was under the impression that the difference between the 250 and 350 was simply the spring packages --- that the frames were identical.
Now... the Excursions frame is like these, but I also understood it was "fully boxed" but smaller in some sections --- likely as strong. This would compare to the new (yet to be released?) 350 frames that are fully boxed. IIRC, the F150 got it's fully boxed frame a year or two ago.
My 99 F-250 SD has a front section on each frame rail that is replaceable. It is bolted, rivited, welded to the rear section. The split is about even with the front wall of the cab.
