Pro Football Hall of Famer John Madden shows you around his home on wheels, the Madden Cruiser, in this footage from WBAY-TV. The Madden Cruiser is on display periodically at the Hall of Fame.
From what i understand there were 2 drivers as well so i doubt they could have made the operation work unless they were sleeping in hotels at night, not the bus.
Madden always slept in the hotel and left the bus in the parking lot, so I'm sure he had the drivers use the bunks. Spend hours on the road in that bus, I wouldn't want to sleep in it either lol . Especially for a big guy like Madden.
