This is what I ordered from this ARE brochure
If you go to page 4 you will see
Build Your Perfect Commercial Aluminum Cap
I will list what mine is
1 - DCU (035)
2 - 29 inch
3 - A- colour matched B - standard ( no interior skin )as I want to insulate with 1 inch styrofoam. Did not get a roof vent but am going to add a 12 volt fan vent at some point.
4 - I choose Double Full with Windows , this gives doors that are the same width as the wheel wells when open.
5 - I got the Clear Mitered Sliding window for optimum ventilation. I took the latch off the exterior and put on the interior so it can open from inside then put a screen on exterior.
6 - I don't think this was available when I got mine
7. - I got the radius sliders as they come with screens
8 - got no toolboxes or shelves
9- I got the ladder rack with the centre support and third leg
10- I did my own lighting
11- I did not get a camera but still my add one
12- did not get
To the right of # 11 on page 10 you will see a list called Commercial Aluminum Options List and 7 rows down you will see Radius Front/90 degree side walls on 29'' and 36 '' only ,that is what mine is and it give more head room so I can sit up straight
The web site much better now,hope this helps ,if you take this to any dealer it should be fairly easy
