For 2010 the Chevrolet Silverado and GMC Sierra you've got up to 5 engine options and up to 5 suspension options including the Z71 Off Road package or the Z82 heavy duty trailering package. There are also many different exterior packages to accent the vehicle. There is the Chrome Essentials package, White Diamond Tricoat package and the Laser Blue Metallic package. Also there is a Snow Plow Prep Package to add to the versatility of both of these vehicles. Both are also covered by a 3 year 36,000 mile bumper to bumper warranty and the 5 year 100,000 powertrain warranty. I hope this information helps you.
