We are doing a bunch of upgrades this spring to our TT. When its all done we will have new tank monitors, inverter/converter, battery monitor stereo and dedicated pc. My buddy is an electronic guru and very good at designing and installing systems. With all the new upgrades and their accompanying monitors, it only seemed right to replace the crappy plastic tray that holds the factory installed monitors and switches. Here's a pic of the panel he designed and had custom made.
