OceanKing --
Welcome to the forum and welcome to the Newmar family. Both are fantastic groups of people and machines!
I'll confess that until your post that I didn't know Newmar once had a model named Grand Star. A 2008 sales brochure for the Grand Start shows it to be constructed in the usual high quality manner as all Newmar coaches -->

Is this your first motorhome?
When you have a moment, please create a "signature" that provides info about your coach e.g. year, manufacturer, model, etc. as this info will help get quick answers you have from the forum.
Best wishes for many enjoyable, safe adventures in your Grand Star and don't hessitate asking the forum for help at any time!
