Glad that you seem to like the (partial) cockpit view. And, no, not all trucks look like that. I'm afraid that I had a bit of a reputation. It's some computer, some Ham Radio, some entertainment and some combinations of the above.
I'd like to convince you that there was NO steering wheel. Just a joystick. But there was one. The better to rest one of the keyboards whilst going down the road.
I did have a generator or, more precisely, and auxiliary power unit for services while parked. The power up was actually more than 5 minutes but the power down aided by a big red switch.
This is all somewhat off-topic here and I don't wish to transgress. But I've been meaning to put some pics on my Google Web Album for some time. Now's a good time to get it done if you care to see more. I'll return with a link.
