I'm not sure how the drivetrain is built on this thing but I feel like if my diesel pickup would let me to lock the rear diff without switching to 4LO first I could probably get by without 4WD for the most part. Now because of the differential, when one rear wheel slips the other does nothing effecitively making it 1 wheel drive. Not that it changes the core argument though - I'd never buy a truck without 4WD.
