My guess is you have a dead battery. What voltage does it read? should be 12.7 volts for a fully charged battery. So use your volt meter and check and report back what you find and you will get more help after that. When you hooked up the 7way from the tow vehicle you were running off of the Tow vehicle battery and things worked from that fully charged battery. Things did not work from your RV battery because it is probably dead. They don't stay charged all year and you need to plug into shore power to recharge the battery. Report back what you find about battery voltage.
