No I did not camp for 3 days with out any ground disconnected. The ground was always on the ground bar, the only thing I did was disconnect the ground that was terminated on the neutral bar. There was a second ground wire coming from the transfer switch to the neutral bar on my breaker panel. When I did that everything was ok. BUT for some reason, and I don't quite understand why when I got back home I reversed everything that was done at the CG, plugged it in and everything works fine. That was 2 months ago, since then I have been in 4 other campgrounds and never had any problems.
I know it seems strange but maybe someone could check it out and look at their CB panel and see if there is a ground on the neutral bar. The unit have is a 2014 Winnebago Adventure 37F.I had a 1999 Chieftain before that , and honestly I don't know if it was wired that way or not, I never had a power problem with that one, never took the CB panel cover off.
