I dunno if I would consider a fridge and a microwave entertaining
IN my truck I have a fridge, micro, 5000 watt inverter, amp and sub, satellite radio, my laptop. The fridge, inverter, amp and sub are all stock installed.
My laptop and my CB are my main entertainment sources
Also being a Volvo 780 it is quite nice to have the workstation.
I guess keyless entry (remote) would be considered a tech huh.
