I feel your pain Ryan, we lost ours on a trip back to DRV for repairs!
DRV replaced it under warranty, when we returned home I bought a SS eyebolt, drilled a hole in the new door and with a small bungee I have since secured that trap door without losing this one! That was 4 years and at the time seemed like an easy "fix".
A heavier duty door would probably be the "right" fix however.
