Thanks for the info Keith, well at least mine is RC, the cab is a 1/14 scale Tam King Hauler,
like the Tam tanks, it has great engine starting and running sounds, plus air brake, gear change and reversing beeper noise.
The low loader is a converted Bruder flat bed trailer , (that name is obviously familiar to you).
The low loader has repeater, working tail,brake,reversing and indicator lights as on the cab.
Still working (when I get a chance) on getting the ramps to operate via RC.
