2003 Chevrolet Suburban 2500 LS 4WD 4dr SUV (6.0L 8cyl 4A)
Had the 3/4 ton for 9 months now. Wanted 6.0 liter so ended up with 4-wheel steering and all the toys. It's been great driving all over the Southwest, towing a 6,000 lb trailer and three children. Leather, heated seats, DVD panel for children, 4.1 ratio on rearr axle for towing; it's all good. One complaint is the third row gets jarred when crossing speed bumps. Must be that heavy duty, solid rear axle. WARNING: Take a few weeks to get used to 4-wheel steering, especially before towing. Had an unfortunate accident caused by unfamiliarity. I turned front wheels left, rears went right and shoved trailer into telephone pole while "helping" me turn out faster. $1500
4-wheel steering is really nice for parking and tight quarters. Heated seats were a pleasant, winter surprise. Can get 16 MPG on a long run at around 60 mph. Gets 12 MPG around town. Very strong tow vehicle. Lightly affected by our 30 foot, 6,000 lb trailer.
Big Chevy trucks are needing a front suspension component replaced. Been backordered for months. Making a loud knocking sound. Dealer assures us it is common to many 3/4 ton Chevys now. The 4-wheel drive and 4-wheel steering combo was a bit noisy at low speed even before this. Thirsty.
