Rather than worry about running extra wiring consider adding the WF-2030 WiFi module to the Trimetric 2030. Another option is to install a Bluetooth-enabled Victron Energy BMV-712 monitor. Both of these options will allow you to install the monitor in an easy location close to the battery and access it using a smartphone, tablet or computer. I installed a Victron Energy BMV-712 earlier this year. The Bluetooth connectivity works great right out of the box. Configuration is managed through the VictronConnect app on your devices. I haven't looked at the actual monitor itself since it was installed.
Another nice feature of the BMV-712 is when you install the optional battery temperature sensor the Bluetooth allows the BMV-712 to share the battery temp with other Victron Energy devices such as an MPPT Solar controller. This will allow the other devices to optimize the charging based on the current battery temps and avoids having to install multiple temp sensors.
