How I'm preparing for RV travel this year

Last year, 2020 was a tough one and we stayed mostly at home. This year we want to get back to some RV traveling. Before we hit the road, I need to take care of these 6 important items. One for me and 5 for my 2016 Winnebago View. (4K video)
1. Covid Vaccine for me and wife
2. Clean and inspect roof for cracks or loose sealant
3. Check and air up tires
4. Inspect and add water to 6 Volt batteries
5. Install new Temperature gages
6. Replace RV mattress
