Hello and welcome. Did you get it from an outfit like rv wholesalers or a dealership or what? Anywhere that sells them should have given you a pdi (pre-delivery inspection) that includes how to use it. That said I think it would behoove you to find d a local Thor dealership and pay them to do a walk thru with you. This way you can learn to use all of your systems and look for any issues to be repaired under warranty. Best of luck to you.
