If that’s what you want to do a school buss would be a much better choice. Just be sure to buy a ‘County’ bus not a ‘City’ bus which has much lower gears and screams on the highway.
There’s a place in either PA or OH that specializes in them and has a huge inventory that’s constantly turning over, call them and you can ‘reserve’ a shortie with highway gears.
Besides, it’s a bunch easier to remove or cover up unneeded windows than it is to try to install them from scratch were there wasn’t any before.
Also, be aware, if you install electricity (other than 12 volts), propane, or plumbing you could very well be denied a stay in a conventional campground with it.
