Lets talk about the diff between 19.5 and 22.5's on Gassers
Aside from IMO better looks what are the benefits to units with 22.5 wheels on Class A gas units? Can you convert a 19.5 set-up to 22.5's?

Pros: higher weighty rating (but probably not too useful if converting since the rest of the chassis isn't uprated magically), somewhat better ride, perhaps longer life.
Cons: higher cost, heavier weight (which makes it much harder to change a tire in the case of a flat, as well as having some performance penalties that probably don't amount to too much on a motorhome), larger size makes storing a spare rather more difficult.
Many 22.5 setups use a much higher lug not torque than smaller tires and wheels, too, which in turn requires significantly heavier duty tools to manipulate.
Different, but not necessarily pro or con: the diameter is larger, which means a different effective axle ratio, more ground clearance, a higher center of gravity, and possibly interference with the wheel wells or fenders (probably most likely in front).
I would not convert a motorhome I had.
