As for twin beds the older you get the better twin beds are for sleeping in a small trailer. At home a kingsize bed is a mandatory but in the trailer one of us sleeps in the front and the other in the back. Works out great since there is only the two of us. Porta-potty moves to center aisle at night. We have been sleeping together for almost 60 years in the same bed except when camping. We slept in the oueensize bed in our truck camper cab over and climbed over each other as needed when younger but now like to just put feet on floor and get up.
