FWIW, I have taken the dimensional drawings Available from Ford Fleet of the 2004 Excursion and the 250/350, and stripped out the frame outlines.

The Drawings are available in my gallery for you to peruse. I changed the format from pdf to jpg and then modded the drawings.

Also in the gallery are isometric drawings available from Genuine Ford Parts.

Please peruse the drawings, and examine them side to side. You will see that it is as Monsta and I thought, the Excursion is basically the same as a 250/350 up to the drivers feet, and then it changes quite a bit going back.

Add to that th edifference in metal thickness, the web height, and crossmember differences, This is a different critter.

I think maybe this will end some confusion.

 

Good post Bion! Might want to label those photos to help newer folks.

 

Well done!

You've finally put an end to an age old debate!

 

OK, just for the 'ell of it, I figgered out a way to get some better images on here.

Excursion Frame:



F250/350 Frame:




I think this makes for a better comparison. This should help.

By the way, the F250/350 drawing was of the 137 inch wheelbase, same as the Excursion.

 

Unless the drawings aren't to scale the Excursions frame looks smaller in diameter.

 

Looking at the drawings by housedad, if you used F250 springs on an EX you would get a lower ride height, Which we all know is not the case. I could not see the diagrams in the origional gallery.

 

I would think its becouse of the long floor boards in the Excursion and the truck bed needing to be raised.

 

Here are the original drawings. You can print them out for yourselves to compare.

The two drawings are NOT to exact scale. The f250/350 drawing in the post above is slightly larger.

 

Here is some more stuff:

No matter what I do, I can't seem to get the pics to the right size for scaling. One of these days I'm gonna have to learn to use photoshop.

 

Im pretty sure all 250's or 350's do not carry the same bends. Is the truck frame a regular cab Super Cab or a Crew Cab? That will make a differance and of course if its an Excursion. The floorboards will be longer as the truck gets longer. Hence the longer streight portion in the Excursion frame.

 

The F25/350 frame above is of the standard cab 137" wheelbase pickup. for comparison, I have the F250/350 Crew Cabe frame stripped out below.

The frame or the excursion is based on the Superduty frames, but it is not the exact frame of the 250/350 that many have claimed. It is designed differently in the back half as nessesary for a different body style and a different mission.

OK I'll give in . There different but there the same. The long flat area is where the floor pan would be for the cab, the differance is the floor pan goes all the way to the back on an Excursion.

 

I accept that there are some differences between the Excursion frame and the different Super Duty truck frames. What I am seeing here is that the differences are due to floor plan differences. I think that you are saying that this is the case, and that you are not saying that the Excursion frame is not as robust as the Super Duty truck frame. Is this correct? Or are you saying that the Excursion frame is not as robust?

 

RIGHT! Im saying that the Excursion is a full on One Ton truck and frame.
