Exactly the point I was trying to make — to plan the improvement in a way that makes most sense based on budget and intended need/requirement. To me it makes little sense to add a second A/C to then find out you can’t run it off the generator because you didn’t select the correct unit (as in a more efficient model). That assumes you’d want to run both A/Cs without shore power sometimes.
I looked a little closer at FE24 in question and it appears to be a Mercedes Sprinter-based full-wall-slide motorhome which normally comes with 13,500 BTU/hr A/C and 3,600 Watt propane generator. That’s indeed a lot of motorhome for a 13,500 if parked in sun on a hot day. The slide has 4 windows so if possible should be parked with slide facing north.
