I am assuming you store your View under a carport, is that correct? Because of that, I would get four wheel covers
to keep the rubber tires out of the direct sunlight. I would also close the blinds and put in place a front & side window cover
I do not have any experience with the Lithium Ion batteries and your charger, but for my Ford E-450, I just keep it plugged-in with the house power switched on, and I run a maintenance charger from a house 120 VAC outlet and back-feed the motor's start battery through a cigarette lighter power plug. I don't know if your dashboard power plug stays hot for you to do this, but I would certainly keep the coach battery on a maintenance charger as well.
I would leave the refrigerator switched off, and both doors open a little bit so it doesn't mold inside. I would shut-off the Air Conditioner and not let it run unattended.
