Ya you're right mine does, I have to get a lot more measurements. its hard now because my current setup is in the way and its a very tight fit and hard to remove.
It gets wider as it goes up because the wheel wells are in the way on the floor, and then the panels stick out on the sides, so the top would fit into where the window is. you can kind of get an idea of the sides here. http://jeep.fremont-online.com/uploaded_images/jeep_ladder-716549.JPG
that is what the box would basically look like. I have an overall height of 36", 58" wide at the top, 50" at the mid section, 39" at the bottom, depth of 29" at the bottom 18 at the top. I feel this isnt enough room lol.
I have a 2003 Jeep GCL and i am wondering if I can fit 2 21 inch Wardens in the rear storage area, a ported box would be optimal. I am just unsure if I have enough volume in order to fit the box. If anyone has any experience with the storage capacity of a jeep please help out.
