2003 Chevrolet Silverado 2500HD 4dr Extended Cab LS 4WD LB (6.0L 8cyl 5M)
Get the diesel/Allison combo! I have experienced 23-27 mpg cruising at 70 mph, 16-17 city. Even factoring in the higher price of diesel, the cost per mile has been less, and with unlimited power and towing ability. Only annoyances have been rattling steering column and body squeaks and rattles. Otherwise truck has been very reliable. Comfortable and with very good brakes and handling.
I bought this truck to pull a 10,000 trailer part-time and eventually pull a much larger trailer. Never got the heavier trailer. New engine fuel milage was disappointing. Fuel mileage got better as engine broke in. 15/20 empty and 12 pulling. At 53k miles engine spun power steering pulley off the shaft. Replaced PS pump, pulley and serpentine belt. Next week blew ERG pump.
Does everything as expected. Plenty of power, plenty of room. I am very happy with this truck. Just the typical minor maintenance stuff. It pulls my boat like it's not even there. 13 mpgs isn't bad for a 7000 lb. truck.

I have had 2 Ford trucks and had nothing but trouble with them. This 2500HD is my 2nd Chevy and this truck is the best by far. I love driving this truck on the road. It handles very good in all kinds of weather. I have only 1 complaint. The "bad gas mileage
2003 Chevrolet Silverado 2500HD 4dr Extended Cab LS Rwd SB (6.0L 8cyl 5M)
I love this truck! The 6.0 litre is powerful and smooth. With a locking differential and 4.10 gears this baby hooks for a 2wd. The one big complaint is bad MPG I average 12 to 13 no matter how I drive it; city or hwy. As far as its intended purpose it huals everything I want with no effort! Including, but not limited to cornering at 60-65 with a big heavy trailer and tractor very little sway and with the HD trans and cooler it never gets over 160 degrees with a load. Interior very spacious and well laid out. The suspension is tight and rides a little rough with no load but who cares its a HD.
HD transmission with cooler, heavy duty rearend with locking diff and 4.10 gears. Rear suspension craves heavy loads. I love the body style and interior layout. Added nerf bars, mud flaps for front tires, HID lights, wire mesh grille, flowmasters, K&N filter, tinted windows, infinity speakers.
6 speed transmission for better acceleration and gas mileage. Lose the plastic tailgate handle
