AC overload
My daughter has a 2004 fifth wheel. We had a 15000 commercial domestic AC put in. Was told it will freeze her out. It's connected to ceiling assembly. Blows cold but can't run on anything higher then ...

I met an RV'er who said he wished his Fifth Wheel's Water Heater offered Electric (120-Volts-AC Power) heating and not just the LP he'd been using.
It was a Suburban brand water heater model SW6DE. "D" means it has electronic ignition called Direct Spark Ignition (DSI) so it can be turned on from inside the coach with a simple switch.
"E" means it also can also heat water with 120-Volt-AC power. I turned the little switch on the heater itself ON and he got hot water without using LPG.
My point here is, that he had NO switch inside the RV. If your daughter has NO switch for 120 VAC inside the coach, only the switch for LP operation, it's possible there is in fact a water heater running off her shore tie power.
The switch is nearly hidden. Open the cover, if it's Suburban, crouch to the level of the cover hinge, and look in the lower left section of the heater. If the Switch is UP (ON), push it down to OFF.
Our coach is a Class C, but it's 30-Amp, and will NOT run A/C and Electric Water Heat in Summer. I'm a little surprised that the A/C Blower Fan is what's making the difference, but do check and make sure the water heater isn't on AC Power.
