Need feedback on new workshop, garage, apartment build

[Charlie2011GT]

Hey guys, I was hoping to get some feedback on my garage and shop design. It's going to be a 30x40 RV garage and a 60x40 shop/garage with a 30x40 apartment above with a loft. Because of the location of the apartment above half of the garage with the other half having vaulted ceilings, I'm having some trouble deciding how many, what size, and where the garage doors should be located. Any feedback on the design or thoughts on where to put the garage doors would be appreciated.
The RV garage is going to be 18' tall, it's not correct on the blue print.
