My father got a TC this summer as a mobility vehicle, with a lift in the back for his power scooter (he has MS)
But I'm seriously thinking of getting one as a mobile DIT workstation. Check out REDUSER.net there's people talking about it there too.
Some guys in LA have a rolling color grading suite in a Sprinter.

I currently have to disassemble my rig to get it in and out of my Focus, which is due for replacement. The TC would have enough verticle height inside for me to work seated at my station, keep me away from the elements.
The biggest thing would be providing enough power from the system. My rig will pull anywhere between 600-3000w depending on the setup, so if I go the TC route, I'll have some planning to do. Also have to figure out A/C and HEAT, and exhaust of the computer systems heat as well, and I don't really want to have a rooftop AC, that would keep me from parking it in a standard garage. Anyone got suggestions for other A/C options? More than likely I'm gonna have to install a bunch of batteries (weight and space) and a big inverter to run everything.
