I knew from my home shore power that 20a is sufficient to run the ac and the frig. Since I had a 30a to 20a dogbone and the pedestal 20a bkr was in better condition, I finished out the rest of the trip on 20a without incident. I kept the wh on gas, since the recovery is quicker.
reading all these comments, I realize that the pedestal 30a bkr was probably worn out.
