Great advice, everyone. I very much appreciate it.
I was seriously leaning towards buying a Tesla Gen UMC package with 14-50 adapter and JDapter, but saw on a different thread a number of people saying they were having trouble with the UMC. Particularly that it seemed it wouldn't bring the Bolt to a complete charge, or that it shut off just before fully charging. That gives me pause. Are these complaints commonplace, or the exception?
