would anyone know if the back flip up bench seat in a 2005 f250 extended cab is the same as the f150 of the same year. im looking on getting a sub box for under the back seat. i can find a bunch for the 150 not the 250. anyone with this set up? pictures and info would be nice.

 

They are different. Starting in 1999 the Super Duty line and the F150 line had completely different bodies. You still may be able to fit it though. I can take some dimensions off of my dad's 99 extended cab, just let me know what you need.
