OK now check each junction along the way to the RV and see where it jumps to 135+
I speculate you will find a loose or corroded neutral wire connection.
Must be out at the outlet?
I tightened all neutrals while I was in panel.
( Umm I don't think they are really called neutrals. Isnt that on a 4 wire? Isn't it common on 3 wire?
I believe Common vs Neutral is the same thing. Although branch circuits are just 120v they still share the neutral(common) with the other side of the panel.
High voltage in a split phase system is generally created when a shared neutral has a poor connection and does not carry the imbalanced load properly. Since the main panel has correct voltage there must be something down stream. Could be in the RV itself. Measure under load as no load will have no issues.
Posted 120v at the panel and 135v in the RV. There must be a point where that changes. Is there a sub-panel?
