2. If a unit fell in my lap and it was 1 AC with 30 amp service, I could factor cost to add 2nd AC as part of the total cost.
Best way to get 2nd AC running off 30amp and 4Kw Generator in order of preferred method.
1. Replace existing 15k BTU with a new 13.5k PS (Power Saver) BTU and add 2nd new 11.0k BTU (Power Saver)
or
2. Replace existing 15k BTU with a new 11.0k PS (Power Saver) BTU and add 2nd new 11.0k BTU (Power Saver)
or
3. Keep existing 15k BTU and add 2nd new 11.0k BTU (Power Saver). Wire to separate 20 AMP breaker, but leave plug where you could optionally unplug from the 20 amp shore service to plug into the 30 amp shore service on coach 30 amp and 4kw generator. In this config you would know that you can't run other heavy stuff at the same time, but if you had need, you could run the rear AC without turning on the front AC.
For me, I would likely try #3 first and when / if the 15k BTU had any issues, I would downgrade it to 13.5k BTU

Replacing a 15k with a 13.5 is an expensive option to save 1.7 amps. Better off leaving the 15 k alone and just purchase the smaller unit for the bedroom. Basically your option 3 is what I do, I just installed an additional 30amp receptacle right above the original, I have the option of using the 30 amp or use a reducer and run off the 20 amp circuit on the power post.
