Traded my 07 FX4 with the 5.4 in for my 21 Limited. I do miss the keypad on the door. I miss the center console shifter as well. I keep grabbing for it especially in curves. Other than that my Ram out performs the Ford in every way. A WHOLE LOT MORE POWER! Especially with the iDrive throttle performance. Holy crap did this wake up the truck!
My a/c in the Ram has its days. Some days it's blowing so cold that I have to turn it down. Some days I would be better off just rolling the windows down. Now I think, I think, this might be an issue with the 12" touchscreen. I've had the maps mess up on me, backup camera image constantly goes out and XM shows no signal at times. The dealership said they have seen this before and they have to replace the touchscreen to fix it. I just take pictures each time it has a problem so they can see what it does.
Other than that I don't miss my Ford at all and I had that truck for 14 years.
