I did the explorer thing and all it wanted to be was an Expedition. So I got and and have never looked back. Millage is the same or better than the Explorer especially in the highway. Repairs are cheep (It is a ford).
Explorer will get it done but you will always be wanting more. Expedition will get it done with out issue. Mine is There are heavy duty versions that have tow packages (what mine has). I like the XLT packages as they are a nice mix of function with enough luxury to make it a very comfortable daily driver. The limited or eddy bower ones are usually sprung softer and have way to much leather and cheep looking expensive stuff that dont belong in a ford. It is a ford truck not a Cadillac after all mixing the two just does not work in my book.
5-7 k will get you a nice one from 02-04 if you shop around. The only thing to look for is the 100K service. IT will cost you about 2k but is very well worth it. They also have coil packs that tend to die after 100-120K of service but they are simple to change and I just keep 1-2 in the rear storage. A simple code reader will tell you what cylinder to change.
Other than that mine has been rock solid simple to maintain,, easy to drive even in the city and will tow 7000lbs with out braking a sweat (I have the towing package in mine)
Bottom line shop around find a lower optioned one with the heavy duty suspension and tow package and you will get it for short $$$$ because ti does not have the DVD or power but scratchers. What it will do is be a truck that can hall 6 adults, gear and tow a car with out issue.
Ohya they are absolutely unstoppable in snow. The full time all wheel drive system is great.
One other thing that was a big seller was the adjustable peddles. My wife is 5' nothing and as she put it is the first at that she can get the seat steering wheel and the peddles in the correct place. It was my truck but very quickly became here daily driver.
