 This is the second Excursion I've 
owned. The first had the V-10 and 
really bad mileage.  The 6.0 diesel is 
very powerfull and gets GREAT mileage 
for the size of the vehicle.  On the 
highway, I average 24 MPG at 75 MPH.  
My Jeep Wrangler gets a paltry 15 MPG's.
We have had a few minor, but annoying 
problems, particularly electrical ( A/C 
looses power.. just shuts off ) but far 
less than the problems we had with the 
2000 V-10 ( also electrical, interior 
lights would blink on and off everytime 
it rained and it rains a lot in 
FLorida ).  Overall, this vehicle 
represents the best value for people / 
cargo around.
