You are saying once the RV is on the road, your "alternator charging " will keep the voltage up enough for the inverter to handle the surge and load until you get back on shore power.

Or just don't take it to work and suffer the extra time from going back home to get the rig. What is worse?
Turn off the display when you are in storage with no shore power and want less draw from the batteries.
