Here's something different. I use the hell out of my Fiesta to haul a lot of camping, running and photography equipment. I took the back seats out over a year ago, never put em back in. I was getting annoyed with putting everything in the back in a weird way so I used some leftover 30x30 extruded aluminum t-slot to build this.
Eventually I'm also going to build an "addon" platform that will take the place of the passenger seat, which should all me to sleep in the fiesta when I need to(winter/rain).
This, plus my thule roof rack and hitch platform mean I can haul a lot of stuff. It's pretty funny. Plus I can still pull ~37mpg on the freeway/interstate with all this gear.
