Looks like Franklin is a pretty small town, like mine. If other things are similar, that could mean that you'd have to provide a car. Its a bigger challenge than it sounds like due to wear and tear, and mostly brake pads that go fast. Gravel roads? 100 miles a day of that will beat you down.
It could also mean only 2-3 days a week at most, but who knows? The Postmaster would hopefully be honest and tell you. RCAs are worked 6 days a week in some offices, and 1-2 in other, tiny places. Large offices use RCAs as low-paid whipping boys to avoid hiring higher paid "regular" carriers.
This sounds strange, but ask if the office delivers Amazon, and how long that has been going on. Rural carriers do not get paid by the hour. They are paid a set amount each time they run the route. At one time, it was pretty fair. Then came Amazon. The routes suddenly got 3 times the packages to deliver, but got no increase in pay. It has ruined the job in many areas.
The only bright point is beginning Sept 28, the PO will pay 75% or so of your family-type insurance costs. Major benefit that we didn't have before.
