We talked with a couple who were in the Rocky Mountains and her husband had a heart attack while driving...she had to get the rig under control and drive down the mountain.
Told my husband no and no and no.
Had retired military friends who were full time for many years. Last I heard their road equipment got more expensive and the military pay was reduced. They had to rent housing and default on rig and get jobs.
Talked to people who tried it and they agreed first two years was fine, then they wanted a place to light.
