Picked this up with less than 100 miles on it and have put 1,500 on it so far. Fuel economy for highway driving averaged 24.7 mpg for the first 1,400. I have no complaints and it exceeds my expectations in every category. I enjoy the jake brake and like the way it works.
Diesel engine, 6-speed automatic transmission, and jake brake. Six passenger capable although I haven't had six yet.
Can't think of any so far. Maybe after I have put on a few thousand miles.
