Genuine GM Accessories 17803488 Underseat Storage Box - Durable Car Organizer for Trucks & SUVs - Perfect for Storing Tools, Cables & Emergency Kits

I was very dissatisfied and returned the Underseat Storage Box and had to argue with Amazon about a full refund including shipping. Chevrolet altered the floor in the 2014 Silverado and the "Genuine GM Accessory" Underseat Storage Box DOES NOT FIT!I argued with Amazon and ultimately obtained a full refund including shipping.The construction of the Genuine GM Accessory was very good. It is better than the aftermarket Underseat Storage Box that I obtained from another source at a higher price. It is too bad that GM did not alter the box to fit the modification GM made in the floor of the vehicle.
