2006 Chevrolet Silverado 1500 Work Truck 4dr Extended Cab 6.5 ft. SB (4.3L 6cyl 4A)
Find that the Chevrolet extended cab work truck is an excellent value. Lots of room inside and good comfortable seating. The V6 is challenged to cruise in hilly areas without having to ramp into higher rpms, but does a good job on the highway. Most of these have exhaust vibration as mention by another reviewer. Transmission is smooth and brakes are responsive. I like the hood design for 2006 which is very rare. 21 mpg on the highway is a plus and access to the motor is easy.
21 mpg highway with good cabin comfort. You can use the back seat for adults for a couple of hours (you can't do this on many of the competitors extended cab models). Chevrolet is ready to deal and the price is very competitive. My last Chevrolet truck with a 4.3 lasted 15 years with low maintenance.
Figure out what the vibration is in the exhaust on this motor. Speakers are either low quality or the factory radio is the problem. Switching to another radio involved a $100 fee at radio installer due to the design by Chevrolet in the wiring to several other electrical components. Kept Chevy unit
