Good to see you found us. You can pretty well find answers to any problems you will encounter on this site.
If you haven't taken a tour of the Tiffin Motor Home manufacturing plant in Red Bay, Alabama you should take the time. The tours are free and they have a campground next to the plant that is very reasonable and you will meet a lot of Tiffin owners. You can also have work done on your coach at the plant.
Another forum you might want to join which is free and is ran by owners of Tiffin Motor Homes is this one. TiffinRVNetwork
If you find it is worthwhile they do ask for donations to keep the site up. You decide if and how much you want to donate.
