The entry door on our redwood 3921Gk 2017 does not work. It will not stay open not matter what we do. Has anyone else had this problem. Our rv is two weeks old. Plus we can not get the tv in the living room to work on satellite even though the dish works. Any advice will be helpful We are new to this blog so if i am not doing this correctly please let me know what I should do. Thank you all in advance
