Congratulations on your first RV! The internet is full of information, all you have to do is Google it. YouTube is full of videos on how to's on every form and shape of RV. The new tires is a good start as well as having a mechanic check it for you. Some dealerships will do a walk through and inspection for you and teach you some things too. You many want to check a local recommended dealership for such a thing. Their mechanics are well trained and experienced with RV'ing. It would be well worth it to have a hands on walk through.
