It is a 30 amp cord with 110v adapter. Tried two different ones to confirm no issues.
I called my closest dealer where I bought the RV last year (3 hours away), and spoke to one of their techs, very helpful people. He recommended trying to start the RV using the house battery override switch, to see if the solenoid isolator is the culprit. Tried that, then got 13.3v to house batteries. So no Im waiting on a new solenoid from the local auto parts store. Hopefully it solves my issues, worth a shot, otherwise he agrees its probably the converter.
Bummed it still cancelled my 4 day trip, dont want to dry camp if nothing will get power.
Ill update next week and let everyone know how it turns out.
