You have your bus, don't worry about what 'they' say. Do your build and when you find an issue find a way to deal with it. I'm 6'6" tall and knew I'd never find a bus with enough headroom so I know I will have to do a roof raise at some point or get used to slouching in my bus - Oh well! If I find any problems with the bus as I progress I'll find a way to deal with them, so will you.
At any rate, welcome.
