I have a lock (only one, and it's temporary) so I will be attempting to install it within a few days.
I have decided that I will need cup holders on this cab, but no ordinary cup holders, dowels / rods coming up from the sides of the cp (I have not decided exactly where) to hold a max of 4 "ultimate gulps" from 7-11. I have one, and so do just about all my friends ($1.25 for a 2 liter of slurpee, how much better can it get). these mugs measure 5.5" in diameter, but the handles are hollow and have a hole in the bottom so I figure a rod for the handle requires less work than getting actual cup holders.
