I have a standard cab long box Chevy and the only thing that can replace it is my crew cab Super Duty. My wife and I pack light but I couldn't ever go back to my extra cab s10. It sits in the back yard completely Un finished and will stay that way till its scrapped. To small under weight. We can fill either truck up fast we use the crew cab on longer road trips and the standard cab for more off road camping. They both have uses and can tow a small jeep or quads along if we need more.
