"I could do 3 80 miler days carrying the bare minimum and paying for lodging or 5 days and carrying camping gear. I'll not bring cooking gear and will pay for food along the trail. "
Friendly reminder that 80 miles on the trail is much harder, all things being equal, that pavement. The crushed limestone takes about 15%-20% extra energy, especially if the trail is the least bit wet. It is doable of course, but if your pavement limit is 80 miles, you will be tested doing 80 miles on limestone.
