2006 Chevrolet Silverado 1500 LT1 4dr Extended Cab 6.5 ft. SB (4.8L 8cyl 4A)
I owned an F150 prior to buying a 1500 Silverado. The ride of the F150 does not even come close to the ride of the Silverado, the 1500 is much smoother, quieter, and generally a more comfortable ride. I am extremely happy with the Silverado 1500.
The seats have what feels like a lumbar support system, it feels as if there is two bumps or cushions on your kidneys, feels really good.
Maybe to have the rear bench lay more flat in the regular position, it looks as if the seat is at like a 55 or 60 degree angle instead of the 90 or 100 degree angle. I of course have never sat in the back but it looks uncomfortable.
