The Excursion is a dead vehicle. It is being discontinued so resale will be really bad.
The 4 wheel steer in the 2500 Sub. is really neat and makes for a manuevverable vehicle. The 6.0 w/ 4.11 will pull almost anythin unless your boat & trailer weigh over 10,500 lbs than g4et the 8.1.
The dealers should have big rebates on these things.
