bmv -700 dual displays

hi everyone, newbie here. I'm wondering if it is possible to run two displays from one shunt on my truck'. One in the alloy canopy for camping, and another in the dash. Would this work via a double RJ45 adaptor on the shunt? TIA

cheers

Dave

Unfortunately, this will not work.
The BMV unit is more than just a display. It is what actually measures the Voltage drop over the shunt to calculate current. Two units trying to measure the same shunt would very like cause erroneous readings at best and likely other unforeseen problems.
