We have a 2020 and love it. Make sure you disconnect battery per MB guidance when storing for extended times (>1wk) and carry an extra solenoid for the house in case you need to replace. Great fun and lots of memories.
 
You should consider joining the Coachmen Galleria facebook group for lots of details and helpful folks. The solenoid is a soda can sized solenoid isolates most of your 12VDC loads. I have a 2025 Li3 system for it the solenoid is activated when I turn on the Battery disconnect switch. For a AGM/generator system I am pretty sure that the switch is labeled battery isolation. Anyway there should be a row of 12V fuses in your electrical panel this relay is between the battery and that row of fuses. Coachmen just changed their recommended part for this. I don't have the details at my fingertips at the moment but the old one is still a good replacement. There is a list of general stuff on lots of RV pages like surge suppressors power watchdog Amazon.com . . . water pressure regulator, power adapters to go from 50A, 20A, etc. power to the 30A standard power adapter and many other things that hopefully the previous owner threw in as part of the package. Check under the sink for a water filter. Oh a 10 foot telescoping ladder so that you can get to the awning when it goofs up. Figure out by Sept. how to winterize the system so you are not out there some night when it is about to go below 25F trying to figure that out. Coachmen's web page has an owners page where you can download all of the component manuals. Oh on the MB battery buy a battery maintainer (Make sure it is a maintainer not a charger). Amazon.com On the 2016 there should be a cigrette ligher outlet that is always on indpendent of the ignition. Also consider buying a portable jump starter. I have one but am considering repurposeing it to a different car and getting a combo jump starter and tire inflator. Amazon.com Oh and I don't know the part numbers but they use a standard relay on a number of the systems plus there is a coil on the propane solenoid on the newer models that likes to fail.
 
Super good advice from TomVA...I've found Coachman technical support to be helpful in working through problems you might encounter. Also Coachman Owners groups have useful hints and tricks to make your experience with challenges much easier. Enjoy!
