In addition, you should try to ensure dealer provides as much as possible such as Water hose, Crapper hose, Shore Power extension cord, outdoor gas grill, Choc blocks, etc... never hurts to ask.
I'm sure this list is not complete... seems like there's always something else. Suggest continue to use the FR Forum as this is a great resource where folks are happy to help when you have a question. Lastly, YouTube is also a good resource that can "show" you how to do or operate things.
