Your coach came with a 1000 watt inverter with 4 ga wiring from the battery to the inverter plus a 150/200 amp fuse. A 2,000 watt inverter requires 0/2 ga wiring and a 350/400 amp fuse. Normally the 1,000 watt inverter has a 15 amp bypass with 14 ga wiring; where as, the 2,000 amp uses 20 amp bypass with 12 ga wiring. Typicality a 2,000 watt inverter idling current is more than twice that of a 1,000 watt inverter and this has a bearing on the part load efficiency.
