My husband & I had just purchased our first 5th wheel, a 2000 Coachman with one slide. When we towed it in, leveled it, we opened the slide out so my parents could see the inside.
My father (aged 85) motioned me over to the side & whispered real low: “You better make sure to drive close to the right of the highway so no one will hit that room sticking out. That looks mighty dangerous!”
I tried not to laugh but gently told him that the room slid inside & locked when we were towing it.
