Most of the coaches which are solar ready will have wire running from the roof to the charge controller. If they do provide charge controller, most of the time it will be only 10amp, and can handle only 100 watts comfortable. you can follow the wire coming from the roof and follow, it should be going in the charge controller. If not then there will be only wiring for you to hook your own CC. You also might have to run your own wire from CC to Battery bank. You can check by calling thor if there is wiring and fuse present and also the size of wire. 30 amp charge controller can hold up to 400 watts. Thor usually installs 10amp if you have one. Its only to keep your batteries charged. if you like to have more solar power you can upgrade to 30amp. But make sure your wire can handle that.
