rear brakes and parking brake leave something to be desired. Rear rotors rust decreasing overall braking power and make the parking brake all but useless. Good power and excellent towing vehicle for horse trailer. Two piece drive shaft failed during our second towing excursion. Dealership replaced with a single piece unit. Now it hums while you drive but has proven to be reliable. Unit stuck in 4wd during -20 degree weather. Again dealership repaired. Dealership was cooperative in making repairs.
This plain, Jane GMC has a 6.0 liter engine with a 4.10 rear end. Not good for fuel mileage, usually about 14, but has ranged from 9 with a trailer in the wind to 15 on a flat highway. Warranty work on a jerky transmission, radio failure, rattle in the steering shaft, center console latch, and noisy heater fan. Not much really. Basically satisfied & hoping for a long run.
