If you don’t use “Use Separate Dashboard Layout”
in the vehicle profile settings… Torque will treat
the displays, pids and data logging as global in
scope.

You could also export then reimport the display
layout if you want to maintain separation since
its likely the some of the pids maybe unique
to each vehicle.

(This of course assumes Torque is working on
your Truck stereo).

When a profile with separate dashboard layout
selected is used any displays added are then
associated with that profile only.

Changing to a different profile will use its defined
private or global displays.

I would export the desired dashboard layout
then..

Assuming your Truck is running another version
of Torque you will need to send the exported
file (name?.dash) to its corresponding folder, then import into
that app. (Hidden folder .torque/dashboards).

Your screen sizes may be different
between devices so you might need to long
press displays and change sizes under display
configuration menu to clean it up.
