I lived in a 35' Bluebird for about three years. It had been partially converted so I could cook and sleep comfortably but the toilet/shower setup wasn't hooked up and I just used KOA or whatever facilities.
Plenty of room after the seats are removed so I used the area in front of the rear wheels as my living quarters and used the area behind the rear wheels for my tools and bike. Had no problem getting my Shovehead through the rear door.
Had a 25' Bluebird for a short time but ended selling it to Rick at Strokers of Dallas who made it into a beer bar to handle the overflow from the ice house beer bar.
The only problem I ran into, and not a problem really, was that they were both geared pretty low for around town and not really suited for highway speeds. On smaller roads they were perfect.
Check out Rolling Homes: Handmade Houses on Wheels by Jane Lidz https://www.amazon.com/Rolling-Homes-Ha ... 089104129X It's got some great ideas and pics of bus and truck modifications.
There are also a number of other books and some neat videos on Youtube on converting buses.
