Got to RV park, shore power resolve AC & GFI issues, so problem is power coming from 7500 generator, 9000 hrs, talked to my hometown RV tech, he had me check transfer case for burnt wires on gen side or loose. Found no issues. 800 miles home from New Mexico to Texas, very hot! So going to leaving back AC off and run gen for residential frig and front AC. Anyone got thought on issues? Thanks for help!
