Hello and welcome from Michigan as well.
By "Thor 24.1" I'm assuming you mean Axis or Vegas 24.1 (since I don't think any other Thor motorhome has that model #). If so the first thing you need to do is download and read Ed's excellent crowd sourced owner's manual:

The first thing I would do after purchase is get the alignment checked--even though it is a used unit you can't assume the previous owner did that (they should have). After that have fun (my wife drives our Axis frequently).
