Thank you all for your advice!!
I have not been back to the camper yet, but I will look for the water heater bypass. I know the access door for it is on the back of my TT so I will start there. And I will look into the maxxair covers. I've decided to buy a 3-stage/smart charger for my battery and just keep it charged at home in between trips.
Feel free to continue to share your opinions/advice!! I'm sure I'll be back soon with more questions!!
