Dinette bed weight limit on a jayco featherlite?

For some extra insurance....after adding some adequate screws or even bolt through, consider making a couple of 4x4 "legs" to go underneath the dinette in the bed position. You could add something a simple as sticky velcro to hold the leg to the base and maybe a larger block to stabilize in the floor so it doesn't slide out. We never use our dinette for other than a dinette, but you're right, there's not much support there.
