First, for everyday charging you charge at home while you sleep, just like your phone. And just like your phone when you wake up you have 100% range. For the model 3 long range that is around 300 mile. While you can charge from any 120 volt outlet, for your usage I suggest 240 volt charging from either a dryer type outlet or a dedicated circuit like a NEMA 14-50 for faster charging. Teslas come with a power adapter for 120 volts and the NEMA 14-50. Other adapters are available for different plugs. The price to charge depends you electrical rate. Charging 300 mile costs is about $12 here in California and $4 in Atlanta. Most people charge at home or work or at public chargers, except when they travel.
Second, regarding your travels, 99% of the people in the US are within 150 miles of a Supercharger. if you go on Interstate 80, 70, or 90, there are Superchargers every 100 to 150 miles. They are usually located at places where you can get food, go to the bathroom or shop such as restaurants, shopping malls, Starbucks, etc. parking lots. With a Supercharger you can add around 300 miles of range in one hour. But you can add 200 miles in 25-30 minutes. The best thing is the cost. For Model X and S the cost to use superchargers is $0.
Looking along I-80 supercharger stations are in Ogalla, Gothenberg, Grand Island, Lincoln, and Council Bluff. Here is a link to the supercharger map for the US centered on Nebraska.

Third, maintenance on a Tesla is minimal. There are about 20 moving parts in the drive train. They have regen braking like your Prius, so as you know the brakes last forever. But any maintenance like oil changes, tune ups, cooling system maintenance, etc do not exist on a Tesla.
Fourth, a lot of Prius owners are moving to Teslas. The Prius has been the car most traded in for the Model 3.
