Welcome to the forum:
To answer your question, no. You would need to buy new wheels in order to run the 22.5" tires. However simply changing the rim size will do little to nothing to change the rolling diameter of the tires. You would have to check into the specifications for each tire size. Also if you change tire size to a bigger tire, you are in effect changing your gear ratio so, your power goes down, your gas mileage goes down and your speedometer will be off.
Being that RVs have a long wheelbase it is common for them to bottom out if the break angle of a driveway is just right. I have never bottomed in the middle of the rig but will drag the tail in the right situations. Rollers can be added to the frame at the rear of the rig though to help with this and are available through RV suppliers.
