If there has been high turnover in your territory it will be hard to sell as the clients have products that have not been properly implemented and are likely gun shy to purchase.
It will also depend how “over promised/under delivered” their experience with new business is.
The work/life balance can, and probably will, become very toxic. You are on the road constantly if you have a travel heavy territory which makes it difficult to get admin work done during business hours. You will be working before and/or after work - probably on the weekends as well.
Ask for transparency in your territory assignment. You want to know how far your furthest client is as you will have to go see them in person at some point
