Comments for a A.R.E. MX Shell Rack design?

Hello,

I have a Prinsu Cabrak that I really love, in addition to a RTT and ARE MX Shell. I couldn't put a cap rack like some of you guys have on your shells since the MX has a higher roof than the cab, and there isn't an alternative on the market that matches the Prinsu. Anyways, I've been tinkering with CAD and designed this aluminum rack side that can be mounted to the top of my MX - yeah, inspired by Prinsu. Anyways, I have a cost estimate of $150 to laser cut andnpowder coat two of these - they are about 36" long and would be mounted as end caps for three 47-inch long Prinsu-type bars for a total of about $200 (3 bars + these two aluminum sides). The rack would then be mounted to my Yakima style tracks that are already on the MX. Any comments? Yes- wanted to put the R2D2 logo on it (no extra cost). I could put the taco truck there too - easy to customize. The extra holes and tabs are to mount an ARB awning to it. Any comments about the overall design? Please note I am not selling this as it is for personal use only (Im following other copyright restrictions). I just wanted to see if anyone here has any good design suggestions to make this better. Thanks!
