My 2013 Silverado 1500LT Z71 with a 6.5′ bed, runs great and has been extremely reliable with only repairs to wearable items, like breaks, tires and wheel bearings. I installed a new alternator last year, but it turns out the old one was fine. The battery was the problem and is less than one year old. The front wheel hub assemblies (wheel bearings) have approximately 50K miles on them. Tires will need to be replaced soon but not immediately. There are weathertec floor liners front and rear. As you can see in the pictures there is rust above the rear wheels, but overall the truck is in good shape.
