Does your 30 to 50 amp adapter work on normal shore power (like at a marina)?
I was told by other members of our owners club (differerent Luhrs Group brand) who have the same and similar boats a smine... but are newer and have isolation transformers.
The discussion came up in the context of occasional charging while on the hard. I didn't really understand, partly because I don't have an isolation transformer... and partly because my simple chain of Marinco adapters worked fine... even though they said that same adapter chain wouldn't work for them because of their isolation transformer.
So I mention it, in case germane for OP's situation.
Can't tell if your second question was for me, or for OP... but if for me, my adapter chain was Marinco 15A to 30A, Marinco 30A to 50A... in our marina's back lot. Bunch of years ago, now, since we seldom winter on the hard, and since we've found we don't need to fool with charging the AGMs over winter anyway...
