We had the upgraded escape hatch in our 2015 Mammoth. It was manually operated, and was a welcome addition to the cabover area. We special ordered a better escape hatch for our 2017 Mammoth that also is made by Dometic, but is remote-control operated. It is much heavier duty than the manual model and is about three times as expensive, but we're very glad Randall agreed to use it in our build. I'm not sure if Host has the remote-control one on their website, but it's worth checking out. Either manual or remote escape hatch is worth the added cost in our opinion.
