Can I run 15,000 BTU air cond with RV plugged into my house?

I have 39ft Gulfstream Friendship 102 diesel class A. My 15K roof air works when under generator power, but overheats and trips breaker when the RV is plugged into my house. I have a normal 20 amp outlet on my house. I use a 50ft, 10 gage cord from the house to the 50 amp cord on the motorhome. If I shorten the 10 gage cord, is there a chance that my household power will be enough to power the air conditioner? In my current setup, the voltage to the air conditioner drops from 119 (no load) to 101 (full load). While on generator power, it only drops to 113 volts full load. I like to hang out in the RV in my driveway. What do I need to successfully run the 15K roof air, other than use my generator? I am also considering putting a portable air conditioner in the RV for driveway use instead of using the roof air. Your thoughts?
