07’ Chevy box truck

Selling my 2007 12’ box truck. It’s got a brand new motor and transmission with only about 15,000 miles on those. This truck is a 1 ton. I personally have loaded it down and towed a trailer behind it with ease. And I mean 75mph down the highway, and still had to get up and go. It also has a speaker system like no other! As well as LED lights all the way around it. It also has a bully dog tuner. I would hate to part with the truck, however if someone is interested I will let it go.
