Truck off-road question

[f5fstop]

Remember the video a few months ago with the super Chevy off-road truck (with JR)? If you do, let me ask some questions.
This truck bed has a rail system, as do all 900 truck, that allows easy attachment of accessory items.
So, what would an off-roader really appreciate in added accessory items that could be easily adapted to the truck rails.
I have come up with a hi-lift jack attachment, fuel/water can holders, a spare tire mount attachment (both vertical and horizontal), possibly even some type of cot setup with folding cots and a tent attachment.
Anyone think of anything else? (Yes it is work related...just maybe GM is starting to look seriously at the off-road truck market, small as it might be.)

Now, if there was a PTO device that was powered by the engine that created 120 volts, what attachments, other than compressors and a refrigerator full of beer would be items that people might want?
