All the wheels should be the same but one never knows who has done what before you got the unit.
The wheel model number, (if ALCOA) is stamped on the inside. That means you can read the number off the rear outside dual. It is a little more difficult to read the number on the front rim while it is installed as it will be on the axle end to view.
I have some info here:

My chassis is raised rail and yours is straight rail, so I can not say yours is equipped with the same rims. Also, Alcoa changed the rims at some point and now only offer the 8.25 as the standard rim.
You may not have room to carry a mounted spare if you have straight rail. Why not just carry a tire, and the service guys can change that on the road. It takes up less space and is lighter to handle and carry. Weight is always something you have to watch with the lighter chassis.
Stop by any tire shop and they will be glad to tell you what rims you have.
The mounting system for these rims changed about these years, (stud or hub centered) so ask an expert before you spend any money.
