Battery question
Two brand new 12v batteries in parallel. The meter on my leveling system shows 12.1 and my handheld tester shows 11.8. Should there be this difference? Have been plugged into 50amp shore power for three days

You should be reading around 13.6V everywhere after 3 days plugged in. If not, your charging system is either disconnected from the batteries, broken, or not plugged into the 120V system.
Check 12V fuses, the 120V circuit breaker, or a 12V disconnect switch.
HTH;
John- some thing not right new batteries should be over 12.6 ea.
- Are you unplugging shore power, then waiting several hours so the batteries can rest before testing the voltage using both the RV system and handheld meter?

What is the voltage at the batteries while plugged in to shore power?
