Just a tid-bit about the Ford E350 and E450 standard wheel base choices.
Last I recall, 3 wheel bases were offered. I don't know what is available for 2021.
- 138" (most often used in the ~21 foot lengths)
- 158" (most often used in the ~24 foot lengths))
- 176" (for the longer)
If the motor home you are considering has a wheel base other than the 3 mentioned, then the frame was modified, either lengthened or reduced by a Ford approved outfitter. The change does not affect the Ford warranty.
On a personal note, I am comforted in knowing that my chassis was not modified. The affected parts from such a modification are stocked well for my rig through the life of my motor home.
Taking as an example, a 24’ M/H, what the OP was talking about, and even if it’s on a 176” (14’ 8”) wheelbase (most aren’t), if for round numbers there’s even 3’ ahead of the front axle that means there’s still 21’ behind the front axle. But 21’ minus 14’ 8” means there’s 6’ 4” behind the axle (7’ 10” if it’s on a 158” w/b).
There’s definitely a stretch in the frame regardless.
