Have a 35ik cedar creek 5th wheel. Can you safely install a window a/c unit, 5k plugged into a 115 volt on a 15 amp breaker, that has other things using the same circuit? One of my a/c roof units is busted and waiting on repair, but need to try to cool down the inside more in Florida. I had tried a 12000 btu free standing a/c unit and it kept popping the main breaker during hotest part of the day so I took it back. popped the 15 amp breaker a few times too. Did not want to chance a fire. Any suggestions as to if I could do the 5k unit?
