Per the TX DMV website a CDL is not required if your bus is "designed" to carry 15 passengers or less, so I "think" this means you dont want more than 15 passenger seats permanently installed,
I would suggest you get your bus titled as an RV and get your class B non cdl license before you put the rack on the roof, I dont know if they will question whether or not it is an RV or some other type of commercial vehicle if you have a rack on top intended to support people,

per this manual,
"" Who is exempt from a CDL? (Certification form CDL-2
4. A recreational vehicle that is driven for personal use ""
My reading of the regulations leads me to believe a class B non cdl is sufficient if it is for personal use,
I would also suggest that you make no statement on the site or in an email regarding you wanting to use this vehicle in a "for hire" status, It will definitely change what type of insurance you need, perhaps other things also,
I have spoken to several texas peace officers and they all swore up and down that a class b is not needed for an RV regardless of its weight, but the regulations I have read seemed clear to me that they were wrong,
I got my class B non cdl because I dont want the hassle of some court or attorney overriding the street cop if I got in a wreck, especially since if I was found to be driving without the correct title or drivers license my liability insurance would be cancelled retroactively.
I assume you will drive like a granny with that rack on top, I assume the rack weighs about 4000lbs, your bus is probably 17000 empty, so this adds up to 21000 with the rack,
Just installing a spartan interior will add 4000 lbs which means by the time you are done you will be near the suspensions max weight,
I recommend you keep decent tires on it and make sure they are G rated, IMHO you dont want to overload the tires as well as the suspension, and G rated tires on that bus can support about 39000 lbs,
Be sure to confirm its legal max height, I think it is 14 ft,
I "think" nothing can stick out more than 4 inches from the sides other than side mirrors, 3ft from the front bumper and 4ft from the rear bumper,
