The Bay is so different from the Lake. The heavy breeze is keeping the lake open. Things calm down Fri to Sun that will most likely freeze the lake over. Then we get strong winds again on Mon to Wed that could likely blow it open again. You may be able to fish the bay, but I am doubting the lake. JMHO. I can wait, but I am getting the itch.
I have a 2015 21' Ice Castle RV that has two house batteries. I added the second to the house. It will run the furnace fan all night but it is running a lot slower by morning. There is a noticeable increase in fan speed when I start the generator in the morning. I am thinking of adding a third battery to the house to make up the difference.
