I agree with Chance. GM Tech did something simular (look at the end of "Before you buy a 2nd ac try this first" thread) with his RV and he said it worked fine. I think he used the 15000 + 1100 BTU AC's on 30 amp service Axis/Vegas.

Set the 15000 BTU Thermostat lower than the other that way it aways says on. My 15000 say 19.4 amp (not surge) on the sticker so if your other is at 10 amps even your at 29.4. I thing GM tech also said his Onan 4000 tested at 33 amp for total output (if I recall correctly). So as long as you DONT start at the same time you should be fine (But do your research and desided for yourself).

But you will be very limited on what you can run (a few LED lights should Okay but no blowdryers or Microwave at the same time - Maybe one TV be Okay?).

You could always cool down to like 68 deg inside - shut one AC off to run Micro or some other high draw item for short term, then crank up the other AC.

Let us know know it turns out.
