Since we got a bus to convert into an RV, I have been doing quite a bit of research into them, and gathering information which I might find useful. One question which came up was how fast one can and should drive their bus. There is a lot of variation, and many factors which come into play, but given freely available resources on the internet today it's actually not that difficult to figure out.
As I am about to start working on a Bus conversion, I'm finally ready to publish my research notes on choosing a bus for conversion. I'll have more to say later when I have more actual experience doing a conversion, but this material should be of some interest to anyone thinking of doing their own. I spent considerable time looking at buses and reading both school bus and professional bus driver forums before we made a purchase. Specific information on equipment will be largely applicable to the USA.
I grew up a poor white boy-child in Santa Cruz, which means that there were three ways in which I was privileged, and only one of them was location. Growing up with a single mother with no car when surrounded by the affluent and mobile meant that those were the only ways in which I was privileged. Any place I did not reach via operation of my Chevrolegs had to be visited via the shame train, also known as "The Bus". And riding the bus incurs a stiff penalty.
