I'd see this turning up on some construction sites and in other industrial applications. As it is, it won't appeal to the crowd of people who buy trucks to show off. But, looking at the specs, it just might appeal to people who actually use trucks for work.
Yes, the built-in 110v/220v power outlets and air compressor would go a long way when your on a remote build site. I can imagine it being very popular with "handyman" contractors you hire to fix your fence or repair a porch railing.
The only other option I might add is a battery charger for hand tools. I know they can plug into the normal outlet but it seems inefficient to go from 400v --> 110v --> 12v.
Some, yes, but I see fewer and fewer 8' beds these days. Most contractors and corporate construction vehicles seem to be the higher trim variety with 5-6' beds and extended cabs.
You can still haul 4x8' sheets, you just have to be more creative and haul fewer at a time. Otherwise if you need so many you'd reach capacity in an 8' bed, you'd likely have them delivered to the jobsite (yes, even if you own a truck).
