A respectful suggestion since you still have 2-ish weeks left. That's a really really long lift time, and the van door motors are rather low power. Why don't you look into using an extra CIM motor through a dewalt transmission as detailed in the
Nothing but Dewalts whitepaper. If you need the hard to backdrive properties of the van door, you can always leave the anti-backdrive pins in the edwalt transmission. With proper gearing you could probably get your lift time down to 3-4 seconds.
