Yes, I went from Expedition to Armada. I am basically a Ford guy. My "other truck" remains a 7.3L F-250 diesel. So why the switch?
First, I saw a decline in the quality of the interior in the new models. My Expey was a '97 model. 4x4, offroad package with skid plates, towing package, etc.
It had the two valve 5.4 engine. It was reliable, but really struggled to tow my trailer and the tranny had horrible gear splits.
The new 3 valve 5.4 is only marginally better and the crappy tranny had not been improved. I borrowed a loaner, did not like the downgrade in the interior and it did not tow much better.
Frankly I thought the Expedition looked better on the outside, but that was just a product of what I had become used to. I would probably have gotten another one until I test drove the Armada.
I fell in love with the engine and drive train. The engine torque is so broad and strong all across the power band and the tranny gearing is perfectly matched to the engine. And it tows the same 8,000 equipment trailer the Expey struggled with like it is a toy on a pull string. (Well, that is a bit of an exaggeration, but there is no comparison). Oh, and did I mention the power and smoothness of the drive train?
The Armada has bigger interior, especially in the second row seating and more convenience features. Seats are way more comfortable.
I understand that the '07 Expey will have Ford's new 6 speed auto, which will help, but that's not going to be enough. Until they wise up and go to DOHC 4 valve heads they are not going to be competitive.
I'm now at 28,000 trouble free miles on the Armada. Never had to take it back to the dealer for anything, ever. I still get a big smile on my face every time I get behind the wheel.
