I hate the push button 4 wheel drive systems, as well as just the lever on the floor. I swear by manual lock out hubs. I have had many problems with auto lockers on both Fords and Chevys. Lock out hubs are easier to maintain and far more reliable. And I think a straight axle is better as well. Personaly I am a Ford man but that is all about vehicles history with me. Fords seem to do better in FL. Good luck in whatever you purchase!!!
