i also like having 2 inverters. I use a 2000 watt inverter to run things in my bus, but i always keep a spare. I've found a 700 watt inverter is plenty to run nearly everything in my bus, so i keep one of those handy in case of inverter failure. Mostly due to operator error, but i've killed several inverters in the past few years.
