We have a new 2019 Forest River Premier A212HW a-frame with an electric extend/retract mechanism. When we extend the roof, it lifts it almost all of the way to the locked position, but it never quite gets locked in. We have to manually push up on the lower side to lock it in. When it retracts, it does detach appropriately. Is this normal or should the extend switch take it all of the way up?
