If it has load range E tires (especially if they're GY Marathons) on it don't accept it, load range G should be minimum. DO NOT sign anything til every thing, no matter how small, has been repaired to your satisfaction & DO NOT let them rush you, if it takes all day so be it. DO NOT let tell you "we'll fix it while you sign papers", after you sign they don't care if it gets fixed, it's yours. You will find things after you get to use it a few times so make a list, don't take it back for every little item, present them the list & state when the parts arrive you'll bring it in to be repaired in a timely manner. Dealers are notorious for parking your rv out back "while waiting on parts" that no one has ordered yet. Hopefully your dealer is reputable & takes good care of you.
