MD3060 vs Allison3000? (Might be a silly question)

Hi there!

My partner and I are buying a bus and think we’ve honed in on the perfect one! Wanted to see if I’m being a goober - is theMD3060 the same as an Allison3000 or are they 2 different ones?

The seller is going to send me the serial this week but if they’re the same, I’d like to make the offer now instead of waiting.
