Let me wade right into this shark pool
D sorry john) and give my penny's worth.
I believe that I read not long ago about a pretty big recall on the Sequoia...just can't remember what it is about.
My GMC has about 128k on it 5.3 liter 2003 model and I had to pull the anti lock brake fuse to get the truck to stop. As the front axles wear, the sensors that tell the brain that the wheel is moving or not, stop sensing movement and take over braking and you start to come to a stop and the truck would keep going and you could take out the garage or hit a car stopped in front of you.
Now each time I get in the truck the anti-lock brake light goes on and stays on, and takes over the information panel of the dashboard. This happened on both a 2002 and 2003 but the 02 had extended warranty and the dealership replace the axles and said, "boy you are lucky cause that job is expensive."
Apparently this is a problem that most of these trucks will do at slow speed because the NTSA has a bulletin on it and explain exactly what to do to fix it if you can find the parts at the dealership. In my opinion, this should have been corrected by computer chip, disabling the anti-lock braking system at speeds below 10 mph; you should be smart enough to take your foot off a brake peddle if the truck starts to skid at this low speed.
I don't think the Ford trucks do this. Probably a different system altogether.
Also the spart tire carrier can get pretty useless if you don't lower it down and keep it greased once in awhile. They lock up there and you can't get the tire down if you have a flat.
And another thing is that the transfer case (4x4 unit) has a pump in it that can slide back and forth (too much wiggle room) inside the case and wear a hole in the case causing fluid to leak out and toast the transfer case. My tranny guy said he replaces these all the time. He has a bracket that can go around the pump snugging it up, weld the case hole back up...it is pea sized, and puts it all back together again with fluid, which is about $1500 out the window.
Again I haven't heard of this happening to a Ford. I don't know, maybe GM fixed this problem(s) but when you have these issues and have to pay to fix them, that should be added to the cost of owning this truck.
The last issue I had with it was a fuel pump that crapped out going 65 mph down the road with 18 footer trailer behind it...but I think those fuel pumps can go on any of these trucks.
I did own a 2004 6 liter 2500 and it had tons of power, but never cracked the 12 mpg issue on the gasoline consumption meter....which today is VERY important.
Otherwise no complaints about power and work.
