2005 Ford Explorer Sport Trac XLT Premium Rwd 4dr Crew Cab (4.0L 6cyl 5A)
The only flaw I have found is the rigid and light rear end causes some stability issues. Often at normal road speeds, hitting bumps when going any direction but straight can cause the rear to skip a little, not a fun feeling. I would pass on the power seats if you want to be able to store anything under them, and the rear seats don't fold down flat if you store anything of size under them. Other than that, a wonderful truck.
Styling of the truck and the interior capacity. It was the only mid-sized truck that I found I could sit 4 adults comfortably in 2004. The power rear window is cool. The bed does well for it's size.
Biggest one - Rear suspension, weight dist to increase stability. Interior storage areas. Rear seat folding design.
